Secrets of Strixhaven Promos

Increment (Whenever you cast a spell, if the amount of mana you spent is greater than this creature's power or toughness, put a +1/+1 counter on this creature.) Whenever one or more +1/+1 counters are put on Berta, add one mana of any color. X, T: Create a 0/0 green and blue Fractal creature token and put X +1/+1 counters on it.

This creature enters prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.) At the beginning of your end step, if two or more creatures died this turn, this creature becomes prepared.

T: Add C. T, Pay 1 life: Add one mana of any color. Spend this mana only to cast an instant or sorcery spell. 5: If this land isn't a creature, it becomes a 2/4 Wizard creature with "Whenever you cast an instant or sorcery spell, this creature gets +1/+0 until end of turn." It's still a land.

Draw X cards. Then you may put a permanent card with mana value X or less from your hand onto the battlefield tapped.

When this land enters, choose a land card name. Activated abilities of sources with the chosen name can't be activated unless they're mana abilities. Lands with the chosen name have "T: Add C." T: Add C.

Flying, vigilance Each instant and sorcery spell you cast has casualty 1. (As you cast that spell, you may sacrifice a creature with power 1 or greater. When you do, copy the spell and you may choose new targets for the copy.)

This land enters tapped unless you control two or more other lands. T: Add U or R.
