Flying (This creature can't be blocked except by creatures with flying or reach.)

Whenever one or more creatures you control attack, they gain indestructible until end of turn. (Damage and effects that say "destroy" don't destroy them.)

Haste

Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)

Tap all creatures your opponents control. Creatures you control gain lifelink until end of turn.

Put a +1/+1 counter on each creature you control. You may search your library and/or graveyard for a card named Gideon, the Oathsworn, reveal it, and put it into your hand. If you search your library this way, shuffle.

Whenever you attack with two or more non-Gideon creatures, put a +1/+1 counter on each of those creatures.

+2: Until end of turn, Gideon, the Oathsworn becomes a 5/5 white Soldier creature that's still a planeswalker. Prevent all damage that would be dealt to him this turn. (He can't attack if he was cast this turn.)

-9: Exile Gideon, the Oathsworn and each creature your opponents control.

Put a +1/+1 counter on each of up to two target creatures.

Riot (This creature enters the battlefield with your choice of a +1/+1 counter or haste.)

Flying

{3}{R}: Skarrgan Hellkite deals 2 damage divided as you choose among one or two targets. Activate only if Skarrgan Hellkite has a +1/+1 counter on it.

Whenever an opponent draws a card, that player may pay {2}. If the player doesn't, you create a Treasure token. (It's an artifact with "{T}, Sacrifice this artifact: Add one mana of any color.")

First strike

Whenever Syr Alin, the Lion's Claw attacks, other creatures you control get +1/+1 until end of turn.

When Venerated Loxodon enters the battlefield, put a +1/+1 counter on each creature that convoked it.
