Tucking effects
Some of the tucking effects can go to the top of the library, so I play some "cast off of top of opponents library" effects, for the LOLs.
The Mindslaver is a joke; while Mindslavering someone I tuck their general into their deck. If I was actually serious about this, I would add Black and play more Mindslaver effects.
Not the most powerful deck (needs more creatures), but this deck is amusing anyway.
Ink-Treader is just for the colors, although cast a tuck effect on it can be silly.
