Whenever a nontoken Satrapy you control enters, create a token that's a copy of it, except it's a 1/1 blue Spirit creature in addition to its other types.
Tap seven untapped Satrapies you control: Exile cards from the top of your library until you exile a nonland card. You may cast that card without paying its mana cost.

Enchant non-Army creature

Enchanted creature doesn't untap during its controller's untap step.
Enchanted creature has “{4}: Untap this creature. If it untapped this way, put a stun counter on it.”

Sacrifice this creature: Counter target instant or sorcery spell unless its controller pays {X}, where X is this creature's power.

Whenever you cast your first noncreature spell each turn, you may draw a card. If you do, discard a card.

When Truthseeker Prodigy enters, amass Soldiers 2. Then target player mills X cards, where X is the amassed Army's power. (To amass Soldiers 2, put two +1/+1 counters on an Army you control. It's also a Soldier. If you don't control an Army, create a 0/0 black Soldier Army creature token first.)

Look at the top four cards of your library. Put one of those cards into your hand and the rest into your graveyard.
Flashback {2}{B}{G} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Counter target spell unless its controller pays {2}. If there are three or more counters among permanents you control, counter that spell instead.

• Target creature gets -2/-2 until end of turn.
• You gain 2 life.
• Amass Soldiers 1. (Put a +1/+1 counter on an Army you control. It's also a Soldier. If you don't control one, create an 0/0 black Soldier Army creature token first.)

Whenever Blackfeather Cleric enters or attacks, exile target card from a graveyard. Put a +1/+1 counter on Blackfeather Cleric if it was a permanent card. Otherwise, you gain 1 life.
Surpass {5}{B} ({5}{B}: Transform this creature. This costs {1} less to activate for each counter on it. Activate only as a sorcery.)

Flying
Whenever Elite of Mahara attacks, exile up to two target cards from graveyards. For each permanent card exiled this way, put a +1/+1 counter on Elite of Mahara. For each nonpermanent card exiled this way, each opponent loses 1 life and you gain 1 life.
