When Apprentice Summoner enters, search your library for a creature card with mana value 1 or less, put it onto the battlefield, then shuffle.

Draw a card, then reveal any number of creature or land cards from your hand. You gain that much life.

First strike, haste
Wanderlust — At the beginning of combat on each of your turns, if you control four or more differently named lands, you may pay {1}{R}. If you do, create a 4/4 red Dragon creature token with flying and haste. Exile that token at end of combat.

When Disassociate enters, exile target creature until Disassociate leaves the battlefield.

When Ema, the Traveler enters, reveal the top five cards of your library. Put any number of legendary cards revealed this way into your hand and the rest on the bottom of your library in any order.
{2}{B}: Another target legendary permanent gains indestructible until end of turn.

Flying
Once each turn, when an opponent draws a card while they have more cards in hand than you, you may draw a card.

Flying
Other creatures you control with flying get +1/+1.

Target nonland permanent phases out. (Treat it and anything attached to it as though they don't exist until its controller's next turn.)
Draw a card.

Enchant nonland permanent
Enchanted permanent's activated abilities can't be activated and triggered abilities of enchanted permanent don't trigger.

Flash
If a card or token would be put into an opponent's graveyard from anywhere, exile it instead.
