Sometimes, mana just isn't enough. Several cards in Modern Horizons 3 will give you energy counters that you can use to power up spells and permanents you control. If you can assemble a deck full of these cards, you'll have lots of energy counters and plenty of ways to spend them!

Ixalan also marks the return of double-faced cards. But instead of showing a creature transforming into another version of itself, the double-faced cards of this set highlight the tales and tools of discovery.

Bestow is an ability that appears on some enchantment creatures. Creatures with bestow can be cast as creatures, just like normal, but they can also be cast as Auras targeting a creature. When the enchanted creature leaves the battlefield, the Aura with bestow will stop being an Aura and go back to being a creature on the battlefield!

Many cards in this set reward you for improving your creatures by referring to "modified" creatures. A creature you control is considered modified if it has at least one counter on it, if it's equipped, or if it's enchanted by an Aura you control.

Eldrazi are here for a long time, not a good time, unless they're on your side. Annihilator is a triggered ability that makes some Eldrazi creatures even more brutal when they attack.
