Credit to Zerix. I stumbled upon his/her Ivy Lane combo deck and felt compelled to make a list of my own with the cards I already had lying around. This is admittedly a worse list than the one Zerix posted, but I made due with what I had on me.
I have a similar combo to his: sacrificing
Rendclaw Trow
with Bloodthrone Vampire repeatedly, as long as Ivy Lane Denizen is on the battlefield. This gives an infinite amount of power to bloodthrone vampire. I includedRancor, which when enchanted to bloodthrone, ensures I can get infinite damage through blockers.
Similarly, with Viscera Seer on the battlefield along with rendclaw trow and ivy lane, I can scry as often as needed to find the bloodthrone.
Zerix also had an infinite life combo, by saccing persist creatures with ivy lane and Essence Warden on the battlefield. I don't have essence warden, but wanted to mimic an infinite life combo. It's not as good, but I included 3
Devour Flesh
in the list. Not only can I have the opponent sac a creature, but if I needed to, I could sac my own huge bloodthrone vampire and gain all that life (say in the face of removal). With my 1-of Deathgreeter on the battlefield, I can gain infinite life similarly.
I'm also running
Putrid Leech
, as an efficient beater/ blocker when needed, and Sign in Blood, as it helps me dig to either hit land drops or find combo pieces.
