Ghalta and Mavren

(As a Siege enters, choose an opponent to protect it. You and others can attack it. When it's defeated, exile it, then cast it transformed.) When this Siege enters, up to two target creatures each get +2/+0 and gain vigilance and haste until end of turn.

When this creature enters, choose one — • This creature gains haste until end of turn. • Destroy target artifact or enchantment.

Ward 3 (Whenever this enchantment becomes the target of a spell or ability an opponent controls, counter it unless that player pays 3.) When this enchantment enters, exile target nonland permanent an opponent controls until this enchantment leaves the battlefield.

When this creature enters, incubate 2. (Create an Incubator token with two +1/+1 counters on it and "2: Transform this token." It transforms into a 0/0 Phyrexian artifact creature.) 5: Transform target Incubator token you control. Double the number of +1/+1 counters on it.

Whenever Borborygmos and Fblthp enters or attacks, draw a card, then you may discard any number of land cards. When you discard one or more cards this way, Borborygmos and Fblthp deals twice that much damage to target creature. 1U: Put Borborygmos and Fblthp into its owner's library third from the top.

As long as you have one or fewer cards in hand, Djeru and Hazoret has vigilance and haste. Whenever Djeru and Hazoret attacks, look at the top six cards of your library. You may exile a legendary creature card from among them. Put the rest on the bottom of your library in a random order. Until end of turn, you may cast the exiled card without paying its mana cost.

Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for 1 or one mana of that creature's color.) Tap up to two target creatures. Put a stun counter on either of them. Then put a stun counter on either of them. (If a permanent with a stun counter would become untapped, remove one from it instead.)

Flying, first strike, haste Whenever Rankle and Torbran deals combat damage to a player or battle, choose any number — • Each player creates a Treasure token. • Each player sacrifices a creature of their choice. • If a source would deal damage to a player or battle this turn, it deals that much damage plus 2 instead.
