AlfaWall

[Arc]

Well, working with Death Nymphs gave me this idea... And through my forum searching, I didn't find any other deck like this.

The main play of this deck is to use Alfatoxin on the opponent's played creatures, creating Malignant Cells and killing them with Fire Wall. Powerful combination, but there's some holes that most decks can agree with. Thankfully, there wasn't too much of a downside to using this deck, and it works nicely for CC.
Feel free to leave opinion about this deck. 

Results of Areas Dueled

AI 3: 95% Win rate. If the AI uses Reverse Time methods, this deck won't do as effectively as needed, and can cause some losses to occur.

AI 2: 100% Win rate. Almost in any situation the Fire Wall makes easy work of the AI. Lobo effects do tend to slow this deck a bit.

AI 1: 100% Win Rate of course. Regardless of the AI 1, most of them won't really harm you due to the speed the deck has.

I'm presently unsure of the AI 4, False Gods, Arena, and PvP, but if anyone would like to test, that would be grateful of you. Thank you!

Not many people have 5  nymphs, but I think no more than 2 people have 5 UPGRADED ones.

There's little to no point in using Fire Buckler for killing the Cells you've created since Death Nymphs can kill off the Cells the next turn before they begin infesting. This means the Cells take damage from infection before splitting.

That said you can still use the Fire CC to make the stall more viable against other threats that will pop up, and speed up the death by infection that is your goal. Ultimately I'd rather skip the Fire part and dedicate more to the stall though. Bone Walls are the best rush-stoppers in the game and they work well with Greys since you get two deaths per opponent creature. Skull Buckler and Solar Buckler are two other good choices; unfortunately the latter doesn't work with Sanctuaries. With less card space wasted you also get more room for the Light part of the stall.

Only 8 towers for 5 nymphs (who have to show up fast), their abilities and 2 Arsenics looks like starving at first glance. quanta is also rare with an average draw. I agree with the idea to remove the fire part in favour of bone walls, as well as more quanta.

I'd use skull bucklers instead of fire shield, as it can block the cells and you can use more deck space for other support/control cards.
