Apex Devastator

Nov 10, 2020 · Each of Apex Devastator's four cascade abilities will look for a nonland card with mana value less than 10 (Apex Devastator's mana value). This doesn't change even if one or more of the spells you cast because of those cascade abilities has cascade itself. Each of those additional cascade abilities, if any, will refer to the mana value of the spell that caused it to trigger. In other words, each cascade ability cares only about the spell that caused it to trigger, the stack can get messy, and we wish you luck.

Nov 10, 2020 · Each instance of cascade triggers and resolves separately. The spell you cast due to the first cascade ability will go on the stack on top of the second, third, and fourth cascade abilities. That spell will resolve before you exile cards for the second cascade ability. The spell you cast for the second will resolve before you exile cards for the third, and so on.

Jun 18, 2021 · When the cascade ability resolves, you must exile cards. The only optional part of the ability is whether or not you cast the last card exiled.

Jun 18, 2021 · Cascade triggers when you cast the spell, meaning that it resolves before that spell. If you end up casting the exiled card, it will go on the stack above the spell with cascade.

Jun 18, 2021 · If the card has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

Jun 18, 2021 · You exile the cards face up. All players will be able to see them.
