Innistrad 3.0 is starting off strong with a strictly better version of the Unsummon effect in Fading Hope.
Zombies is getting a huge flag-post synergy card in Champion of the Perished which is leading me to consider putting more actual zombie cards in the cube. I'm already adding the Rotten Reunion although I think decayed will negatively impact this card more so than in MID limited. At least they can still be used for sacrifice effects, which leads me to Ecstatic Awakener a one time sacrifice outlet with decently sized payoff.
Red gets another shatter effect with an extra mode in Raze the Effigy which is desperately wanted. I'd kill for a smaller Abrade. +2/+2 will have to work and I know heroic cards and aggro decks aren't complaining.
Candletrap is similar to Kirtar's Desire, the coven ability might prove too difficult attain. Chaplain of Alms appears underwhelming at first glance but first strike is a very strong keyword, especially on the flip side with the extra power.
Lunarch Veteran: adding another soul sister to the list of potential includes for the lifegain archetype is never a bad thing. I think I'm still waiting for the 4th life gain payoff card, but maybe the life itself should be enough. We're approaching critical mass of life gain cards.
Consider: just about every blue card draw spells see more cards than Consider. Instant speed is nice, but I don't even run Opt because it just doesn't see enough.
Crawl from the Cellar: Potentially an include if Zombies become something I more heavily support.
Deathbonnet Sprout: Really thought about including this, but it's slow and fighting against other green creatures is rough as it isn't an elf. It's SUPER cute though!
Larder Zombie: the large toughness on this guy is is main selling point. Tap 3 to surveil is nice but I couldn't convince myself to include it here. Definitely one to take a second look at later.
When I initially made my assessment of Trickster's Talisman I didn't notice that it gave +1/+1. Giving blue a Short Sword with the ability to sometimes be a clone is pretty big to me.
I think it's time to test if Brainstorm is too strong in the cube. Brainstone is going to take more convincing.
