>>25315282Mega Turbo is a little more restrictive as to when you can play it. Elixir helps you mill faster. It also lets you make cute plays like if you go second you can attach to a bad starter, elixir xerneas, drop garden and still get off Geomancy. I'm not sure it is actually worth playing, but it is worth trying because Max Elixir is so strong.
Side note, did everyone see this list from Virginia Regionals T8? This is pretty neat given how simple it is.
