Tumblewalker has vigilance as long as you control another Scarecrow.

At the beginning of your end step, draw a card if a creature died this turn. Then Tumultipede deals 2 damage to each opponent if two or more creatures died this turn. Then create three 1/1 green Saproling creature tokens if three or more creatures died this turn.

Menace
Whenever an opponent discards a card, monstrosity 2. (If this creature isn't monstrous, put two +1/+1 counters on it and it becomes monstrous.)

Hexproof

{2}, {T}, Sacrifice Tunnel Map: Search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

Haste
Whenever Tunnel Moles attacks, you may have it phase out. (Treat it and anything attached to it as though they don't exist until its controller's next turn.)
Whenever Tunnel Moles phases in, it gets +2/+2 until end of turn and can't be blocked by creatures with flying this turn.

Reach, deathtouch

Return up to two target creatures to their owners' hands.

Target creature you control fights target creature you don't control. If the creature you control survives, put a +1/+1 counter on it.

Pressure {5}{G}{G} (You may cast this spell for its pressure cost if seven or more cards are in your graveyard.)
Search your library for three creature cards and reveal them. Put one onto the battlefield, one into your hand, the rest into your graveyard, then shuffle.

Archive 5
Eureka! (At the beginning of each end step, you get a research counter if you cast a spell this turn. Then if you have eight or more research counters, remove them and create a Masterpiece token of your choice.)
When you get your eighth research counter, exile Turin's Study, then you may cast any number of nonland cards from the archived library without paying their mana costs.

Return all nonland permanents to their owners' hands. Each player shuffles their graveyard into their library. Exile Turn Back Time.

Choose one —
• Return target creature card from your graveyard to your hand.
• Pay {4}. If you do, return target creature card from your graveyard to the battlefield.

Each player chooses three permanents they control, then returns the others to their owners' hands. Each player loses all unspent mana.
Exile Turn the Record Over.

Flash
Enchant artifact or creature
Enchanted permanent is an artifact with “{T}: Draw a card then discard a card” and loses all other card types and abilities.

Exile target creature. Its controller may profit. (To profit, create a colorless Gold artifact token with “Sacrifice this artifact: Add one mana of any color.”)

Exile target creature. Return that card to the battlefield under its owner's control at the beginning of the next end step.

Enchant creature
Enchanted creature doesn't untap during its controller's untap step.

Choose one —
• Target creature gets +0/+3 until end of turn.
• Exile target creature you control. For as long as it remains exiled, you may cast it, and it costs {2} less to cast.

Trample
Whenever Tusked Consumer or another creature with power 4 or greater enters the battlefield under your control, purge. (Exile two cards that share a type from graveyards. If you do, draw a card.)
Whenever one or more cards are put into exile from anywhere, you gain 1 life.

Respawn (When this creature dies, if it attacked this turn, return it to its owner's hand.)
When Tutorial Boss enters the battlefield, create a 1/1 blue Pirate creature token.

Choose X. You may choose the same mode more than once.
• Each opponent loses 3 life and you gain 3 life.
• Each opponent sacrifices a nonland permanent and you create a Treasure token.
• Each opponent discards a card and you draw a card.

{1}{R}, Discard a card: Draw a card.
{R}: You may put a creature card from your hand onto the battlefield. That creature gains haste. Activate only if twenty or more cards are in your graveyard.

If you would gain life, you gain twice that much life instead.
If you would draw a card, draw two cards instead.
If you tap a permanent for mana, it produces twice as much of that mana instead.
