Artifact Creature â Assembly-Worker
Whenever you cast a historic spell, you may pay . If you do, create a token that's a copy of Mishra's Self-Replicator. (Artifacts, legendaries, and Sagas are historic.)2/2

While resolving the triggered ability of Mishraâ€™s Self-Replicator, you canâ€™t pay multiple times to create more than one token. However, if you control more than one Mishraâ€™s Self-Replicator, you can pay for each of their abilities.
The token wonâ€™t copy counters or damage marked on Mishraâ€™s Self-Replicator, nor will it copy other effects that have changed Mishraâ€™s Self-Replicatorâ€™s power, toughness, types, color, and so on. Normally, this means the token will simply be a Mishraâ€™s Self-Replicator, but if any copy effects have affected that Mishraâ€™s Self-Replicator, theyâ€™re taken into account.
The token will have Mishraâ€™s Self-Replicatorâ€™s ability. It will also be able to create copies of itself.
Some abilities trigger â€œwhenever you cast a historic spell.â€ Such an ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
Lands are never cast, so abilities that trigger â€œwhenever you cast a historic spellâ€ wonâ€™t trigger if you play a legendary land. They also wonâ€™t trigger if a card on the battlefield transforms into a legendary land, as the Ixalan and Rivals of Ixalan double-faced cards do.
If Mishraâ€™s Self-Replicator leaves the battlefield before its triggered ability resolves, the token will still enter the battlefield as a copy of Mishraâ€™s Self-Replicator, using Mishraâ€™s Self-Replicatorâ€™s copiable values from when it was last on the battlefield.
An ability that triggers â€œwhenever you cast a historic spellâ€ doesnâ€™t trigger if a historic card is put onto the battlefield without being cast.
A card, spell, or permanent is historic if it has the legendary supertype, the artifact card type, or the Saga subtype. Having two of those qualities doesnâ€™t make an object more historic than another or provide an additional bonusâ€”an object either is historic or it isnâ€™t.
