Offer yourself to Ulalek and release a mind-melting horde of hungry Eldrazi
Sheoldred, Whispering One The first iteration of Sheoldred, Sheoldred, Whispering One reanimates something from your graveyard on your upkeep and forces opponents to sacrifice a creature on their upkeep
This card is a perfect fit if you happen to have a deck that can create multiple Treasure tokens
An example of unhelpful data is Xanders Lounge: This is an extremely good card, but because its all over the place in Commander, rotation is barely affecting the price
Scoria Wurm - Not that exciting, but its a cheap threat that you could hopefully keep alive longer with Krark's Thumb Mirror March - This can get out of hand really quickly, and there's basically no downside to losing flips Yusri, Fortune's Flame - Designed to be a commander, but it's a solid card to include in the 99 as well Goblin Traprunner - Tons of easy flips with no downsides Squee's Revenge - Can be a huge card draw Planar Chaos - This one can be a bit annoying and might only be good if you also have Krark's Thumb, but it lets you play more controlling Krark, the Thumbless - Similar to Planar Chaos, use at your own risk Frenetic Efreet and Frenetic Sliver - A single card that lets you flip as many coins as you want (you can activate the ability as many times as you want before you let any of the activations resolve, and then even if he dies you still flip all the coins) Puppet's Verdict - A sweeper that let's you control what to kill if you can manipulate the flip As for other cards that I think could fit the strategy of the deck, I would focus on ways to multiply your other effects (extra upkeep steps, copying your permanents, doubling your abilities, etc)
