Rofellos, Llanowar Emissary The mana provided by Sundering Titan This card is miserable at low-power tables, as it blows up tons of your opponents' lands and tends to get blinked, reanimated, or otherwise triggered time and time again
The king of these effects is Purphoros, God of the Forge, which deals twice the damage most other variants do while being far harder to remove
Id play this card only in decks that run lots of counterspells and protection
I recommend to swap them out with dedicated sideboard hate that plays better at stabilizing your board, like Aether Gust or Beza, the Bounding Spring
The card can be nice in an EDH flier tribal deck with Sephara, Sky's Blade or Errant and Giada as commanders or a deck with many flying tokens
Bloodghast Bloodghast is an interesting Standard reprint
