pokemon card dodrio Legendary Collection Colorless Rage (10+) Does 10 damage plus 10 more damage for each damage counter on Dodrio Dodrio Cards | Dex -

The mechanics of TDFCs are not hard to understand

Drastically under-printed, it's only appeared in Urza's Legacy, and as one of those funky-but-divisive Amonkhet invocations

For reference, in current SV-era products a Double Rare lands around 1 in 5 packs, an Illustration Rare around 1 in 12, an ultra rare around 1 in 15, a Special Illustration Rare around 1 in 90, and a Hyper Rare anywhere from 1 in 300 to 1 in 700

(A creature with shadow can block or be blocked by only creatures with shadow.) A permanent with a shadow counter on it has shadow

But often that part of the card is used to stop a triggered ability farther back in the stack if a bunch of instants, especially counterspells, are played and the Epiphany is the last word

In all honesty, this is only a drop in the bucket
