Complete master set (195 main cards + 30 Trainer Gallery + 195 reverse holofoils) via singles runs $1,800-2,800
Radha, Heart of Keld Radha, Heart of Keld really needs an Exploration-type effect in play to pop off, but with an extra land drop or two each turn, Radha can pull together an entire landfall strategy
From left to right: Charizard EX 11/83, Charizard EX XY17, M Charizard EX 13/106

It's also a fun way of bypassing the Reserved List without ruffling any feathers, though hopefully Time Twister and Time Walk don't have their own prepared versions, else this MTG set will be very lopsided in blue's favor
Spirit Monger is another that has gone rather the way of Shambling Shell, despite the power creep it still looks pretty powerful for the mana and would be fine in loads of decks
