Hexproof
When Cantrip Collector enters, rediscover an instant card. (Look at the top card of your library. You may reveal it and put it into your hand if it's an instant card. Otherwise, put it back or into your graveyard.)

Deathtouch
Each opponent's maximum hand size is reduced by the number of poison counters that player has.

Look at the top six cards of your library. Put one of them into your hand and the rest into your graveyard.

Menace
At the beginning of your end step, if Vartrossen Vandals didn't attack this turn, transform it.

Puzzlebox (Begin the game with this and another card you own from outside the game in the command zone, locked. That card is face down until you unlock this.)
{1}: If you control ten or more nonland permanents, unlock Riddle of Entropy.
As long as the revealed card is a permanent card, each nonland permanent you own is a copy of it.

Heroic — Whenever you cast a spell that targets Thassa's Shoreguards, tap target creature an opponent controls. It doesn't untap during its controller's next untap step.
Whenever Thassa's Shoreguards deals combat damage to a player, draw a card.

Exile target creature or planeswalker. Its controller conjures a card named Data-Point into their hand. (It's a sorcery that costs {2} with “Draw a card.”)

As long as Legend of the Wayward is tapped, you may look at and play the top card of your library.

Flash

Enchant creature

Double strike
Distorted (This creature can be blocked by tapped creatures but not untapped creatures.)
Engage (This creature must be blocked each combat if able.)

Manifest the bottom X cards of your library tapped, where X is the number of instant and sorcery cards in your graveyard. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

This spell costs {2} less to cast if you've cast a blue noncreature spell this turn. The same is true for a red noncreature spell.
Menace

Until end of turn, target creature gains deathtouch and “When this creature dies, return it to the battlefield tapped under its owner's control with a +1/+1 counter on it.”

{R}: Paw Valley Wildclaw gets +1/+0 until end of turn. When this makes its power exactly 4, add {R}{R}{R}.

This spell costs {X} less to cast, where X is the greatest power among creatures you control.
{1}{R}{G}: Warriors you control get +1/+0 and gain trample until end of turn.

Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)
Whenever a +1/+1 counter is put onto Lerithan Rebel, it deals 1 damage to any target.

Mine Delver has first strike as long as it's embattled. (A creature is embattled if it has a counter on it or a permanent you control attached to it.)
