Duet — You may play cards exiled with Carnival Daredevil as long as you control exactly two tapped creatures.

Augmented — At the beginning of combat on your turn, if you've spent {W}{U}{B}{R}{G} to cast spells this turn, untap up to one target land you control. It becomes a 4/4 Elemental creature that's all colors and gains haste and vigilance until end of turn. It's still a land.
{T}: Untap target land. It gains all basic land types until end of turn.

{1}{B}: Regenerate Brainless Ghoul. (The next time this creature would be destroyed this turn, it isn't. Instead tap it, remove all damage from it, and remove it from combat.)

Scry 1, then you draw a card and you lose 1 life.

Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)

Double strike
Whenever Eldan Jackson deals combat damage, return target permanent card with mana value 3 or less from your graveyard to the battlefield.

Put a +1/+1 counter on up to one target creature. (Then exile this card. You may play the land later from exile.)

Whenever Dancing Lion attacks, if it was crewed by two or more creatures in the same pack this turn, create a tapped and attacking token that's a copy of one of them. Sacrifice the token at the beginning of the next end step. (Two or more creatures you control with equal power are in a pack.)
