I like the effect of Kessig Cagebreakers , so I decided to build a deck around having creatures that do effects when they die get sacked to beef up other creatures, so that the graveyard gets populated enough to beef up Kessig Cagebreakers significantly.I like the idea of the creatures that I use to sack others for getting lasting bonuses instead of just until end of turn, and I like keeping everything relatively cheap so I don't mind sacking stuff as much when needed.I'm wanting the most help deciding on mana curve, removal, and dredge type effects.

The deck should work like this:
Mana-ramp, play small creatures, and use removal to stall opponent
Play Kessig Cagebreakers
Just before attacking, sack the small creatures to something.
Attack with Kessig Cagebreakers
Acquire Doge army
???
Profit!
