Mobilize 1 (Whenever this creature attacks, create a tapped and attacking 1/1 red Warrior creature token. Sacrifice it at the beginning of the next end step.) Whenever a creature token you control leaves the battlefield, draw a card if it was attacking. Otherwise, each opponent loses 1 life.

Whenever an opponent activates an ability of a permanent that isn't a mana ability, you create a 1/1 white Zombie creature token. This ability triggers only once each turn.

Creature tokens you control have haste. Whenever one or more creatures attack, you may pay {1}{R}. If you do, creatures attacking your opponents and/or planeswalkers they control get +2/+0 until end of turn.

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.) If a source you control would deal damage to a permanent or player, it deals triple that damage instead.

Fabricate 1 (When this creature enters, put a +1/+1 counter on it or create a 1/1 colorless Servo artifact creature token.) Whenever another creature or artifact you control is put into a graveyard from the battlefield, each opponent loses 1 life.

When Kardur enters, until your next turn, creatures your opponents control attack each combat if able and attack a player other than you if able. Whenever an attacking creature dies, each opponent loses 1 life and you gain 1 life.
