Thundertrap Trainer

{1}{U} · Creature — Otter Wizard

Offspring {4} (You may pay an additional {4} as you cast this spell. If you do, when this creature enters, create a 1/1 token copy of it.) When this creature enters, look at the top four cards of your library. You may reveal a noncreature, nonland card from among them and put it into your hand. Put the rest on the bottom of your library in a random order.

Rulings (9)

Jul 26, 2024 · The token copies exactly what was printed on the original creature and nothing else, except it’s a 1/1 (unless that creature is copying something else; see below). It doesn’t copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its types, color, or so on.

Jul 26, 2024 · If the spell is countered, the offspring ability will not trigger, and no token will be created.

Jul 26, 2024 · The token created by the offspring ability isn’t “cast”, so abilities that trigger when a creature spell is cast won’t trigger for the copy.

Jul 26, 2024 · If the spell resolves but the creature with offspring leaves the battlefield before the offspring ability resolves, you’ll still create a token copy of it.

Jul 26, 2024 · In the rare case where the original creature is copying something else when the offspring ability resolves, the token enters as whatever that creature copied, except it’s a 1/1.

Jul 26, 2024 · You can pay an offspring cost only once as you cast a spell with offspring. You can’t try to pay it multiple times to get more token copies.

Jul 26, 2024 · Any “enters” abilities of the copied creature will trigger when the token enters. Any “as [this creature] enters” or “[this creature] enters with” abilities of the copied creature will also work.

Jul 26, 2024 · In the rare case where the creature doesn’t have the offspring ability when it enters, the ability won’t trigger even if you paid the offspring cost.

Jul 26, 2024 · Many creatures with offspring abilities have other abilities that refer to them as “this creature” rather than referring to them by name. This difference is for clarity purposes and does not change the function of any of these abilities.
