Whenever a non-Human creature you control attacks, look at the top six cards of your library. You may put a Human creature card from among them onto the battlefield tapped and attacking. It gains indestructible until end of turn. Put the rest of the cards on the bottom of your library in a random order.

Whenever you attack, if it's the first combat phase of the turn, untap all attacking creatures. They gain first strike until end of turn. After this phase, there is an additional combat phase. Choose a Background (You can have a Background as a second commander.)

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.

Indestructible As long as your devotion to red and white is less than seven, Iroas isn't a creature. Creatures you control have menace. Prevent all damage that would be dealt to attacking creatures you control.

Changeling (This card is every creature type.) Whenever an opponent casts a spell, you may put a +1/+1 counter on this creature.

Flying, haste At the beginning of combat on your turn, up to two target creatures you control each get +1/+0 until end of turn.

Spectacle {2}{R} (You may cast this spell for its spectacle cost rather than its mana cost if an opponent lost life this turn.)

Flying When this creature enters, you may exile up to three other target creatures from the battlefield and/or creature cards from graveyards. When this creature leaves the battlefield, return the exiled cards to their owners' hands.

As an additional cost to cast this spell, discard a card. Draw two cards.

Your opponents can't search libraries. If an opponent would begin an extra turn, that player skips that turn instead.
