Yidris, Maelstrom Wielder Rules Text & Legality
Trample
Whenever Yidris deals combat damage to a player, as you cast spells from your hand this turn, they gain cascade. (When you cast the spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)
Yidris, Maelstrom Wielder is legal in Legacy and Commander, and not legal in Standard, Pioneer, Modern and Pauper.
Yidris, Maelstrom Wielder Rulings
- Jun 18, 2021 A spell's mana value is determined only by its mana cost. Ignore any alternative costs, additional costs, cost increases, or cost reductions.
- 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 Due to a 2021 rules change to cascade, not only do you stop exiling cards if you exile a nonland card with lesser mana value than the spell with cascade, but the resulting spell you cast must also have lesser mana value. Previously, in cases where a card's mana value differed from the resulting spell, such as with some modal double-faced cards or cards with an Adventure, you could cast a spell with a higher mana value than the exiled card.
- Jun 18, 2021 If a spell with cascade is countered, the cascade ability will still resolve normally.
- 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.
