New valkyries and good old Makto [Top 100]

This is the first time I reached rank 100 (currently 99 at time of writing this). The deck is pretty straightforward. Some tips:
While paying contract make sure you can afford it. This is mainly important for the start of the game. The game literally has a loading screen tip saying this. The 6 cost contract of West, On the Trail is quite costly at start of game.
Raniya, Miviox Maniac contract is pretty good against aggro. You can steal a non aegis yeti (which can even be exhausted) and attack with it killing another enemy yeti. This gives you 4 health too and probably causes enemy to rage quit. Raniya has flying and taunt so they don't mix well. Meaning if enemy has ground units the taunt of Raniya is pretty much useless. Also the gain 2 health effect only takes place after the attack phase is complete (just like entomb effect of Umbren Reaper). For example, you have 2 health and enemy has 2 units each having 2 or more attack. If you block one of the units with Raniya and other unit is unblocked, you will loose the game as the 2 health for killing one of the enemy unit with Raniya will be added only after the attacking is complete. Since you have 0 health after attack you loose the game and never gain that 2 health. This is the opposite of lifesteal effect in which you survive as health gain is instantaneous.
In opening hand make sure you have either cheap drops any card up to 3 cost will work or you have Dichro, Conqueror in opening hand (ideally both Defiance and Dichro, Conqueror in opening hand)
If you are stuck on 4 power and have Wasteland Broker in hand, you can broker Halotipped Spray as it has inscribe and even deals 6 damage to enemy if you get to 6 power alive.
Lastly, Pisto, Ever-Churning is good against spell based decks or if you are running out of cards as it is auto 3 card draw if your hand is empty.
