Negative Counter Deck

This is a new deck that I built recently. The idea came from Quillspike and one thing led to another. That's when I decided to make a deck that involves using negative counters.

In order for this deck to run well, make sure you have a quillspike (QS) & devoted druid (DD) in your opening hand. If you have both out in play, you can do the infinite +3+3 combo by tapping DD, let the green mana float, give a -1/-1 counter to DD to untap it, use the floating green mana to use QS's ability to remove the -1/-1 counter to give it a +3/+3 till end of turn. Then you cast rite of consumption to sacrifice QS and deal a ton of damage to a player and gain that much life.

Here are other interesting combos in the deck.
1. In addition to the combo stated previously, if you have flourishing defenses out, you can have infinite 1/1 elf tokens out.

2. If you have Blowfy Infestation(BI) and Carinifex Demon(CD) in play, you can remove a counter from CD to clear the entire board. As you put the -1/-1 counters on the 1/1 elves, they die, and a new set of 1/1 elves come into play replacing the dead ones. As all the tokens die, you place each -1/-1 counter from BI's triggered ability to all of your opponent's creatures, and one back to CD to rinse and repeat.
NOTE: If you have 2 or more BI's in play, it gets more effective.
3. Kulrath Knight (KK) and Pyrrhic Revival (PR) is in the deck to stop the opponent from blocking and attacking. As you revive all of your creatures from everyone's graveyard into play, they come into play with a -1/-1 counter on it. If you have KK out, your opponent's creatures that came into play with a -1/-1 counter can't attack or block.

4. With Necroskitter, if you wipe your opponent's creatures out with -1/-1 counters, they come into play under your control.
