How many extra packs dhould I have for Booster Tutor?
I recently got my hands on a booster tutor and Im very excited to add it to my cube because it's just such a fun card. The question though is, assuming I use extra cube packs, how many extra packs should I keep left over to booster tutor from? With my current set up, It works out so that I have exactly one extra pack but that doesnt seen like enough. I assume I probably need atleast three. Maybe more? I should note that the cube in question is a mono black cube, so the booster tutor is going to be incredibly powerful, but it also means that you probably wont be casting it multiple times per game. In a three round tournament, three feels like enough, but what do you think?
