So, being able to guarantee you get two extra turns sounds like it would be a game-warping card that all extra turn decks should run
Starting with the next opponent in turn order (or, if you cast Flare of Malice on an opponent's turn, starting with the opponent whose turn it is) and proceeding in turn order, each opponent chooses a creature or planeswalker with the greatest mana value among creatures and planeswalkers they control to sacrifice
Therefore, its possible for either a Basic, Stage 1 or Stage 2 to Mega Evolve, as the card itself will specifically state what you can place the Mega Pokmon Evolution card onto (for example, Put M Pidgeot-EX on the Basic Pokmon-EX ) The plan for this is to simply do normal Mega Evolutions, like how they were in the video games
With trample, it punches through chump blockers with ease, and giving another creature that same treatment can close out games in a heartbeat
There may be cases where the signal is just too far away, but a booster will be of real benefit in most scenarios
