Simic Ascendancy Like Revel in Riches, WotC keeps printing better cards that come with +1/+1 counters or interact with them, so its not hard to go off with Simic Ascendancy

You can put together in-color graveyard payoffs like Archfiend of Sorrows, Tizerus Charger, Lucid Dreams and Young Necromancer, and theres enough overlap with the delirium and madness cards to just throw in things like Raving Visionary and Mystic Redaction
Hold the slab up to the light and look at it from all angles
Shroud is nothing to sneeze at
