As for Clarion Ultimatum, the sorcery can do some really powerful things, but we also had a lot of games where it rotted in our hand while we tried to find the mana to cast it, and also a few where we had the mana but didn't really have any good targets (casting a seven-mana card and getting a Birds of Paradise, a Noble Hierarch, and three lands for our trouble doesn't feel all that good)
Also, during this phase, a player may choose to play a card from his or her hand by tapping lands to produce mana
Running it alongside The Reaver Cleaver and Beamtown Beatstick et al is of course going to fuel it reliably, but there wont be a game where this doesnt trigger multiple times a turn cycle
Play Megrim next as well as one of your draw/discard creatures such as the Cephalid Broker or Lore Broker or your force discard/draw creatures such as Barbed Shocker or Abyssal Specter (there are many other Specter creatures that will work as well)
If Possessed Skaab would die, exile it instead.) from Origins
Using a hypergeometric calculator, we can observe that: With a sample size of five, and a population of 99 cards, with 22 being Humans, we would have: 72.4% chance to draw 1 or more of the wanted card 41.6% chance to draw exactly 1 of the wanted card 27.6% chance to draw 0 of the wanted card Our result of 72.4% might go up to around 75% once weve drawn our opening hand and first card of the game, but that math is a little off
