Its both an outstanding enabler and a solid play on turn two, something its uncommon cousins cant say (Zagoth Mamba and Pollywog Symbiote)
This creature should have been cast earlier, like during Declare Attackers step or before that
It still lacks around 15-20 card before I'll feel it's finished (it currently lack any power, any duals, workshop, drain, juzam, and more), but it is at a point where I feel I can sit back and pick up the last cards when I have money and opportunity
Once a players library has been completely exhausted and they are unable to draw from it, that player loses the game
In addition to that, they are treated with a special status, being given a number above the sets cap, as well as a rarity that makes them valuable
