One of my favorite gauntlet decks to play, especially with premium
Poacher's Menageries to make endless premium units. This deck is not particularly fast, but it is highly effective.
Game plan: stall and delete everything your opponent puts out until you can overwhelm them with free units from
Poacher's Menagerie. Extra points if you can get
Martyr's Chains on the board with
Partnership Agreement to kill everything automatically.
Even if it takes a while to draw into this, every one of your units gains you either life or shields. That combined with the stuns and anti-aegis effects of
Furious Magniventris and
Vara, Vengeance-Seeker means you can hold your ground for a while even with bad draws.
Notes:
Don't play multiple copies of
Poacher's Menagerie against decks you know have relic removal, or risk losing them all.
Be careful playing
Partnership Agreement without a board wipe in hand, or risk getting blown out. Or against the Army of Justice deck in general since they greatly benefit from the extra sigils. Or against decks like Harsh Elements that have lots of high cost spells and card draw.
Don't be afraid to hold out for a few turns and sacrifice your units to make your board wipes hit harder, you can always get them back with Argenport Blueprints.
There is a small chance that you will get a
Crill, Merciless Pillager as a 7 cost unit from
Poacher's Menagerie and a 100% chance you will get a
Spirit of Resistance as a 12 cost unit. Both of these will destroy all relics, in turn killing all your free units.
Overall I love control decks with Menagerie when combined with Matko and Flamebathe Reformation, props to the original poster for a fun deck build.
