The most you can do to speed it up is to determine which of the four types of packs (Mystery, Colosseum, Evolution, and Laboratory) the card you want is in, and then duel opponents that reward that type
Its correct to play it sometimes (usually with town synergies), but losses to this kind of thing are just the worst feeling in Magic
A lot of decks and strategies like thatsuch as Living Death, Nature's Resurgence, and Boneyard Wurm
and Raphael, Ninja Destroyer , for example, with flavor text of quotes from Master Splinter that speak to the Turtles' training
This Master is a great addition to any ninja deck, though it's a little awkward that this Splinter reference now co-exists with actual Splinter in MTG
