Mysterio's MirageHow it works & interactions with other cards

Conjuring the Illusion

Mysterio's Mirage features an 'intervening if' clause that checks your actions during the turn. Specifically, the ability only triggers at the beginning of your end step if you have already discarded a card at any point earlier in that same turn. If you have not discarded a card when the end step begins, the ability does not trigger at all, even if you find a way to discard during the end step itself.

Resolution Step-by-Step

First, the game checks if the condition is met at the start of the end step: did you discard at least one card this turn? Second, if the answer is yes, the triggered ability is placed on the stack. Third, as the ability resolves, the game checks the condition again to ensure you still discarded a card this turn (which remains true). Finally, you create one 3/3 blue Illusion Villain creature token, regardless of how many cards were discarded.

When to Deploy the Mirage

This enchantment is most effective in decks that use Looting effects or require discarding for cost. It is important to remember that discarding to hand size during the cleanup step happens AFTER the end step. Therefore, discarding to hand size will not trigger Mysterio's Mirage for the current turn, as the window for the end step trigger has already passed.

Interaction examples

Defensive Illusionary Tactics

Propaganda

If you discard a card during your main phase while Mysterio's Mirage is on the battlefield, you will create a 3/3 Illusion Villain token at your end step. While your opponent faces these tokens, Propaganda forces them to pay {2} mana for each creature they wish to attack you with, making your board state both tall and expensive to interact with.

Managing Resources

Rhystic Study

With Rhystic Study, you might draw a large volume of cards on an opponent's turn. If you enter your own turn and use a spell that requires a discard for its cost, Mysterio's Mirage will see that discard. Even if your opponents refuse to pay for Rhystic Study and fill your hand, the token creation only triggers once per your end step, providing a consistent 3/3 body to protect your valuable enchantments.
