Unseen Chalice

This deck retains the traditional chalice deck 2 main strength:
1) control - Silence from Desert Marshal, Eilyn's Choice quite versatile, and Harsh Rule
2) draw power - Unseen tribe provides Nightfall for drawing power other than chalice's draw power itself

This deck is more resilient than traditional chalice deck because Darkveil Agent covers all our Unseen units with Aegis.
Cobalt Waystone provides aegis to your hero's face, stopped a killing burn spell or a massive Channel the Tempest damage if you encounter mirror!

Unseen Commando provides very good lifesteal to survive aggro deck better than traditional deck. Honestly, this deck is still hard to fight against Aggro deck, but once you survive through first 5 turns, with proper use of tons of 2-drops as blockers, Unseen Commando giving lifesteal, and Harsh Rule for the big green boom, you win the game already because Aggro deck has burnt themselves out and they have no more card advantage against you after 5 turns.

This deck is bigger than traditional chalice deck because of Unseen Commando's buffs
Combo of Humble Instructor, flying Kothon, the Far-Watcher, Unseen Commando, and Shelterwing Rider, you will just fly over them, with really big aegis units because of Unseen Commando buffs + infinite buffing from Humble Instructor. Your enemy has hard time handling that. Not even enemy's Harsh Rule can take them off because of your reproducible aegis.

And Darkveil Agent also provide aegis to Wardwielder making a 2-drop into a huge 5/5!
May your Darkveil Agent always replenish your Shelterwing Rider's aegis! A 5/5 flying aegis unit is a threat, eats a removal becoming 0/5 is still a good flying blocker body!

How to win?
1) survive first 4 to 5 turns and wait for your Crystalline Chalice
2) Surviving is not hard because you have a lot of 2 drops, trade units efficiently
3) Kothon, the Far-Watcher is controversial in a lot of people's eyes, But i think he is good because he is good as an endurance 2-drop in early game, and a strong 6-power ultimate to fly over the top plus summoning a 4/4 owl. The argument of "he dies to Torch is not valid, because if your opponent wants to use removal on him as a 2-drop, your opponent will have hard time dealing with Shelterwing Rider, or other MVPs like Unseen Commando.
4) Humble Instructor is an underrated MVP in this deck because he can infinitely buff Unseen Commando and Shelterwing Rider even after Shelterwing Rider has lost his aegis. Will your opponent want to waste removals on a 1-drop Humble Instructor with aegis? or use removals on Unseen Commando with aegis? or Shelterwing?
5) if you have a chalice target, choose your target wisely not to exhaust that unit inappropriately stopping him from being a blocker. If you don't have a chalice target, use Humble Instructor to buff your units into really big flying units.
6) if you lose board control, Harsh Rule
7) if you are contesting board control, clog the board nonstop with cheap units and chalice them + humble instructor buff them, you will win eventually
8) Channel the Tempest is your routine Chalice deck late game finisher, nothing much to talk about
9) Disjunction and Eilyn's Choice are really good card to ruin your opponent's plan, use it wisely and it should turn the tide of the battle.

Match Ups Strategies:
Againt Aggro:
you have tons of blockers and the ultimate big green boom, and if you survive past 5 turns, you win. lifesteal buys you time. big body from Shelterwing and Aegis-Wardwielder really good blockers. Stonescar is tough, but Skycrag is even tougher (probably hardest match ups) because Skycrag is more aggressive and faster, they may end you easily before 5 turns.

Against Midrange:
Praxis or other time-variant decks.
Desert Marshal is your versatile answer to a lot of threats. Kothon will be good for early and late game after activating ultimate. Your Unseen Commando will eventually gets bigger than their units, with flying and lifesteal, buffs from chalice and infinite buffs from Humble Instructors. Worst case scenario if things get tricky, big green boom Harsh Rule to reset the board. It's all about tempo and their value cards. Harsh Rule is the best tempo swing card, use wisely.

Against Control:
you have too many cheap units. Eventually your opponent will run out of removals to answer your cheap-then-turn-big threats. And you have tons of aegis to deal with that.

Against Mirror:
you have Disjunction to throw the enemy's chalice away. You have Ambush-Silence to answer a lot of things. You have face-aegis to block that nasty giant Channel or Eilyn's Choice to stop their big spells like Harsh Rule or Channel.

Against Armory:
Probably the easiest match-ups. They have a very limited window to beat you. Eventually you will overwhelm them, to make things harder for them, you have Nightfall to chip away their armor bit by bit, and they will feel the pain when your Nightfall melt their Auric Runehammer. Use disjunction wisely and you will win the match without much difficulties.

Against Revenge and Maktos:
not easy, the key card will be Desert Marshal so don't waste your Desert Marshal. Towards late game, you aim to get bigger than their Makto, your Unseen Commando can easily do that.

Against Plates deck: (Deepforge Plate variant decks)
Disjunction, Silence their flyers and pop their aegis, Harsh Rule at appropriate time. Eilyn's choice when they equip big plate on a big body, that's a 1 for 2, that pains them too much.

Against Lifeforce:
They rely on a lot of combos. If unanswered, they will get bigger than your commando and owl. break their card interactions by silence. they have their whole hand on the board with super big units staring at you, harsh rule and that will easily make them concede because post board reset, you will recover faster than them and you win

many more decks which i think i cannot discuss one by one. this deck usually has an answer or two, for those. Minimize mistake and eventually you will find an answer to win.

I have had some very good fights with this deck.
Have fun!
