At the beginning of combat on your turn, if you control a creature with power greater than Ever-Gnawing Rat's, put a +1/+1 counter on Ever-Gnawing Rat.

Trample
Evergrowing Hydra enters with X +1/+1 counters on it.
Whenever another creature you control dies, you may pay {X}, where X is less than or equal to that creature's power. If you do, put X +1/+1 counters on Evergrowing Hydra.

Search your library for a basic land card, put it onto the battlefield tapped, then shuffle. Then if you control seven or fewer lands, return Evergrowth to your hand.

{T}: Create an X/X green Elemental creature token, where X is Evoker of the Ancient Form's power.

When Evolving Elemental enters, scry 3, then reveal the top card of your library. Put a number of +1/+1 counters on Evolving Elemental equal to that card's mana value.

Enchant creature
Enchanted creature gets +2/+2.
Whenever enchanted creature attacks, create a 2/2 white Knight creature token that's tapped and attacking.

Vigilance
{G}, {T}: Exile up to three target cards from graveyards. If two or more of those cards share a card type, create a 1/1 colorless Servo artifact creature token.

Choose two or four —
• Search your library for a Forest card, reveal it, put it into your hand, then shuffle.
• You may put a land card from your hand onto the battlefield tapped.
• You gain 4 life.
• Conjure a card named Fatigue and put it on top of your library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

As Exodus of the Khalizors enters, choose Rehison or Danuri.
• Rehison — Whenever an Elf you control enters, you may move a counter from target creature onto another target creature.
• Danuri — Soldiers you control have trample.

Madness {4}{G}{G} (If you discard this card, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)
Look at the top eight cards of your library. You may reveal a creature card from among them and put it into your hand, then put the rest on the bottom of your library in a random order. Then if this spell was cast for its madness cost, you may put a creature card from your hand onto the battlefield.

Whenever you play a land, you may put a land card from your hand onto the battlefield tapped.

Other Elves you control get +1/+1.
Whenever another Scout you control deals combat damage to a player, you may reveal the top card of your library. If it's a land card, put it onto the battlefield tapped.

Mill two cards, then you may return a permanent card that was put into your graveyard from anywhere this turn to your hand.

You may play an additional land this turn.
Draw a card.

Each player searches their library for a basic land card, puts it onto the battlefield tapped, then shuffles.

This spell costs {2} less to cast if you control an Azra or Demon.
Target creature you control gets +4/+4 and gains trample until end of turn.

Golden age (If you cast an instant or sorcery spell, activated a nonmana ability, and attacked this turn, enter a renaissance for this game.)
Target creature you control gets +1/+0 until end of turn if you're in a renaissance. Then that creature deals damage equal to its power to target creature you don't control.

Destroy target artifact or enchantment. Surveil 1. (Look at the top card of your library. You may put that card into your graveyard.)

Stampede — Whenever Exuberant Hunter and a creature with greater power attack, draw a card.

Reach, trample
Revive {4}{G} ({4}{G}, Exile this card from your graveyard: Create a token that's a copy of it except it has no mana cost. Revive only as a sorcery.)

Trample
Noncreature spells cost an additional “Put a noncreature permanent you both own and control on top of your library” to cast.

You may cast this spell as though it had flash if you pay an additional {1} to cast it.

Destroy target creature with flying. Judge up to one target creature you control. (Honor it by putting a +1/+1 counter on it or condemn it by sacrificing it to draw a card.)

This spell costs {1} less to cast for each permanent sacrificed this turn.
Destroy target noncreature permanent.

{3}{G}: Fallen Forest Wolf gets +2/+2 and gains trample until end of turn. Activate only once each turn.
