Since Templar Knights need to swing to mass tap, I wanted to give them protection from all colors since that's the best we can do not in Blue
Theres a good chance this card will see play in Legacy, Pioneer, and Commander at least
Fifth Floor - 5F items, warp pads, trainers and available Pokmon 5F has a corridor running from top right around the level in a square, a large open room on the right, a small locked room left of it, and two locked room son the left
The other thing that is pretty amazing is that while the deck basically plays almost as much mana as spells, because it plays a bunch of Sphinxs Revelation and scry effects to dig to it in the late game, it essentially creates an interaction where all of those extra lands also draw a card and replace themselves
I guess green could force opponents to put creature cards from their hand into play, but not exactly what I'd call very effective discard effect
