5 rulings from Wizards of the Coast
- 27 January 2026The token copies will have Shredder's abilities.
- 27 January 2026In the unusual case where Shredder becomes a copy of something else while his last ability is on the stack but before it resolves, the tokens will enter as a copy of whatever Shredder is copying.
- 27 January 2026Although the token copies created by Shredder's first ability enter attacking, they were never declared as attacking creatures. Abilities that trigger whenever a creature attacks won't trigger when those tokens enter attacking.
- 27 January 2026If Shredder leaves the battlefield before his last ability resolves, the tokens will still enter as a copy of Shredder, using Shredder's copiable values from when he was last on the battlefield.
- 27 January 2026The tokens don't copy whether Shredder is tapped or untapped, whether he has any counters on him or Auras attached to him, or any non-copy effects that have changed his types, color, and so on.
