This creature reads: Whenever an opponent casts a spell with mana value 3 or less, Scalding Viper deals 1 damage to that player. Basically, if youre against a deck that purposefully keeps their cards cheap, a single copy of this card could end them
Whenever it deals combat damage to a player you make that many 1/1 Elf and Warrior tokens
Its a good way to push some unavoidable damage on your opponents, but it could definitely be better
Another reason to dislike him
Defensive phase-outs like Teferis Protection also allow creatures to dodge boardwipes, edicts and other non-targeted removal, where many flicker effects simply return them to the battlefield in time to perish by the next spell you had been responding to on the stack
Certainly a card that will get played in decks with Seething Songs and Wheel of Fortune style cards
