EndGame

The goal of this deck is simple: find and copy Endra, Champion of Shavka. Enabling that plan is an army of 1-drops, ways to turn each of them into multiple real cards, and the greediest powerbase I've ever built. This has quickly become my favorite Gauntlet deck since Behemoths of Thera released and provided the final piece in Crafty Infiltration (yes, adding the 4th faction improved the deck's consistency). I would not recommend taking this into Throne, because Exploit, Ziat, Steelwarren Reeve, and fast spot removal will absolutely wreck you.

Some individual card notes:

Gleaming Grenadin, Grenadin Drone, Spiny Grenadin, Refuse Roller: These are the fuel for the engine. Each one can give you multiple cards in value when sacrificed to Kindling Carver, Devour, and Display of Menace. You generally want to prioritize getting extra cards in hand because the ramp or draw is usually more useful than another 1/1, so most of the time you'll want to sacrifice Spiny Grenadin or Refuse Roller first if you have the luxury of choice. The exception to this is the AI's quirk of always targeting Rustling over Kindling Carver with spot removal, so it can be useful to sacrifice a Gleaming Grenadin early to give the Carver pseudo-aegis. Try to make the most of Devour and Display of Menace by blocking before you sacrifice.

Sinister Rumors: Mainly a way to rebuy Endra, Champion of Shavka, but the interaction can be useful on rare occasions. It's almost never correct to go for the discard option.

Crafty Infiltration: If you hit a Howling Peak Smuggler you can market the Advantage it hunts - if you already had another card in hand. The Smuggler won't trigger if the Crafty Infiltration was your last card even if you hit the Advantage.

Display of Menace: 9 times out of 10, you want the sac-to-draw option. However, the damage option can be strong in certain matchups - and even more so with a Howling Peak Smuggler or two. You won't really see any relics worth killing in Gauntlet outside of Black Iron Manacles and maybe Xenan Obelisk.

Endra, Champion of Shavka: For some reason, this is the highest priority target in the deck for the AI's removal outside of Patrice, Outcast Queen, so be wary of running it out before you can copy it or rebuy it. However, you do have a ton of ways to dig for more copies or ways to make them, so don't be afraid to play it if you can get immediate value. Remember you can chain multiples to kill bigger things (don't be like me, do the math first).

Mirror Image: Just save it for Endra.

End of Hostilities: Also usually just for Endra, but don't forget it can target the opponent's units too in a pinch. Don't be afraid to market it away in the early game, because it won't become good until the mid-to-late game and sometimes you can't afford a do-nothing card early on. If you don't see it on top and you have at least 2 power, it's safe to activate Kindling Carver.

Replication Cell: Most Gauntlet decks can't (or won't) answer it, so in many games all you have to do is get an Endra into the Mimic Vat and you've essentially won.

Patrice, Outcast Queen: Usually the first card I market for. It's hard to lose when a third of the deck has warp, including the unit you want the most.

Display of Ambition: Draws 2 dead Endras. That's it. If you want removal, grab the Combust.

Token of Purpose: The only marketable option for tri-faction power. You're usually only missing one faction at most, so this is fine. If you want to be a bit greedier, Direwood Pack is fine here too. Fire influence isn't as important because you only have two power cards in the main that can't provide it.

The power: You need FFFPPJS. Sequencing your power can be tricky, but I think the power base I've chosen is optimal until we get the rest of the Paintings (and then it'll be -4 Crest of Fury, -2 Feln Painting, -1 Rakano Banner, +4 Skycrag Painting, +1 Rakano Painting, +2 Feln Banner).
