I played Side Effects consistently in the CT event.
Side Effects gave Trample to a Nissa token stack, but this didn’t create a token beastie when I had Quartzwood Crasher in play.
Quartzwood requires a non-token creature with trample to deal damage. Otherwise, its token would buff itself.
“When a nontoken creature with Trample you control deals combat damage…”
Ah thanks, I hadn’t read the card text closely enough!
