New build, now including Lotleth Troll and Deathless Knight to add more value onto Cat Combo and provide a threat for go big. Switched Dread Wanderer and Gutterbones amounts for Lotleth Troll synergy, added Treasured Find as a two-of emergency button in case Grisly Salvage drops a Tomb, Oven, or Troll.
Gameplan: Develop a highly synergistic sequence of events using Cat Combo (Familiar+Oven), Desecrated Tomb, Lotleth Troll, and some combination of Deathless Knights (preferred for the free return) and Gutterbones.
The Core
Cat Combo - Drains opponent and returns Deathless Knights, free Tomb Triggers, very annoying for opponent to deal with.
Desecrated Tomb - Each cat cycle we'll get an amount of bats (with very technical haste as we're usually executing cycles on our opponents endstep) that we can either use for blocks or to get in some flying pings.
Lotleth Troll - The big boy, every part of this card is helpful, from being able to always pitch creatures directly into our yard to being an annoying regenerative threat, in case our go wide strategy doesn't work we should be able to create a fairly massive Troll with ease as many of our creatures return themselves to our hand.
Deathless Knights+Gutterbones - These two creatures very serve the same very important role which is to be Troll food, return to hand, make bats, be Troll food. As the game progresses and we start running out of natural cards to play we switch from playing GBones and only using Deathless Knights as discard fodder to playing Deathless Knights and using GBones as discard fodder/mana sink.
The Support
Reassembling Skeleton (Reletons) - This is more of an addendum to our core cards, while he doesn't play well with Lotleth Giant OR cat, he's the cheapest natural reanimator for Desecrated tomb so he acts somewhat as insurance against the unlucky hands, Vraska-Releton-Tomb is the poor mans Oven-Cat-DKnight but even if it's less clean Vraska provides card draw to help us out of these situations.
Stitcher's Supplier - The most efficient bin creature has to make the list, Reletons are the best hit here as it is essentially just drawing them, Cat is a great hit if we have Oven in hand as next turn we can sac Supplier to Oven for the Cat, GBones is alright; without combo in hand its possible to still get value but unlikely, DKnight has the highest variance here; if we have the combo ready to set up he's our best bin but otherwise of our main crew we would really rather draw him, and finally all of our other cards get somewhat lumped together as being considered "not fantastic hits"; Supplier and Lands are fine but losing out on any of our combo pieces or set up pieces will hurt.
Grisly Salvage - We're looking for Lotleth Trolls off of this 7/10 times as that's the only creature we can't finagle out of the Yard. Cauldron Familiar 2/10 times in case we don't hit a Troll or already have a Troll with an Oven on board. 1/10 Times we're grabbing a Deathless Knight or Gutterbones because we kept a bad hand and desperately need to play something.
Treasured Find - Between Supplier and Salvage we are potentially dropping 44 cards into our Yard. Obviously that's the extreme case but there will be a lot of self-mill going on, and Treasured Find will be our hedge against losing any of our major combo pieces to self-mill. We only run two here as it's purpose isn't to do anything specific aside from decrease the reward variance of our pre-combo set up.
Vraska, Golgari Queen - Similar to Treasured Find Baby Vraska doesn't do anything specific in our deck aside from being a good utility card and help with bad hands. She can remove creatures from our opponents or just eat some creatures for the card draw (and important lifegain if we have DKnights in the Yard). Theoretically her emblem will push the bats to be entire threats on their own, but if we're Ulting Vraska we're winning the game anyways.
Potential Includes
Woe Strider - Fancy free sac outlet that gives us card selection (the only other free sac outlet in Pioneer to my knowledge just buffs itself and it's the Trolls job to be a big guy), could help in sticky boards where the bats just end up taking space.
