I dont know if Ive ever done in the past too many upgrades to the precons, focusing more on the individual cards that come out, so I thought this would be a fun exercise
Green Dragon Ninja Can Negate 1 Spell or Trap card per turn (Hard Once per turn) and thus makes a good pair with Mitsu the Insect Ninja, who can negate 1 Monster Effect per turn, or with Rank 2 Ninja Shadow Mosquito, who can the Negate the effects of Monsters which have Hallucination Counters, And Lastly, Paired up with Blue Dragon Ninja, who can also Negate 1 Monster Effect per turn
Morbid That creature gets -13/-13 until end of turn instead if a creature died this turn
It's not just about playing the strongest cards
With the Temur Roar preconstructed Commander deck from Tarkir: Dragonstorm, you have a solid starting deck, ready to play right out of the box
