Though Tag Team Pokemon GX come at a steep price of three Prize cards, their speed and strength shook up the metagame with extremely powerful combinations that ended up taking top honors at several major tournaments (like in May when Reshiram & Charizard GX secured both first and second at the 480-player Santa Clara Pokemon Regional)
For this list, Im not considering cards that turn into dragons or double-faced cards/sagas
I've even included some of the cool yet more obscure options like Wren's Run Packmaster, Gnarlroot Trapper, and Wolf-Skull Shaman in here too
Snow-Covered Lands were just that, each of the five Basic Lands had a snow-covered version, which still only gave you one Mana of that color (a Snow-Covered Mountain just produced one Red Mana as does a regular Mountain), but it gave way to things like Snow-Covered Mountainwalk and other such things revolving around Snow-Covered Lands
Nimble Obstructionist is seeing more and more play in Modern, and theres no way it should still be just $3
Prey Upon is the purest form of this kind of removal, but theres cool options such as Bushwhack or Khalni Ambush, which can alternatively be used if you would miss your land drop
