Even just one or two dragons with double strike can turn combat into a complete bloodbath, and if your deck is packed with flying threats, Atarka ends games almost out of nowhere
Paul's card was the only one of those to have been graded as a 10 by PSA (Professional Sports Authenticator), which rates the conditions of trading cards, meaning it is a "virtually perfect card"
It doesnt require a build-around strategy, but fits right into cleric decks that lean into pillow fort or control, pairing nicely with Ghostly Prison and Authority of the Consuls
This allows, for instance, several damage-doubling replacement effects to stack multiplicatively, or for a friendly replacement effect to reduce incoming damage before the opposing replacement effect doubles it
