If it's an Elf, create two 1/1 green Elf Warrior creature tokens
It's colorless, it fits into every single deck, and it costs zero mana to play
Black and green are both secondary at card drawing, both are decent at token creation (although green is a bit stronger in this department), and both are good at destructionalthough what they are capable of destroying varies between the colors (black is good at destroying creatures and land while green is good at destroying artifacts, enchantments, and land)
Here's the original card design: Big, Bad Wolf 3GG Creature Wolf When CARDNAME enters the battlefield, exile target creature an opponent controls with a power less than CARDNAME until CARDNAME leaves the battlefield
This card is crazy, and you should play it
At the end of the day, the downside to Flake Strike isnt much of a bother given how you can use one of Reshiram & Charizard GXs alternate attacks or just activate a switching card (Guzma, Switch, Escape Rope, etc.) to reset the effect and allow it to attack again
