random mtg card Singles Pack (The...WAIT WHAT? Pack) Magic The Gathering Modern Horizons
Description
If that battle became an attacking creature in some way, it would be removed from combat

Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it's too late for anyone to respond

This is very relevant in cEDH, where the mana is basically perfect and you want to be playing the best staples in every color you can
It arguably remained Modern's best creature until the release of Modern Horizons 3
