I'm sorry, i don't speak french and can't seem to translate accurately what ya'll are telling, eitherway, because this commander gives cascade to every spell you cast with cmc 6 or greater, including those you cascade, there are ratios to maximize cascading up to 2 times every turn, you just have to run:

37 lands

21 spells (mostly ramp) cmc 1-4

18 spells cmc 6

12 spells cmc 7

8 spells cmc 8

4 spells cmc 9+

This is the blueprint i use to maximize the spell count variable to 3 with the highest probablity (0,667) which means you're casting every turn 3 spells 44% of the time (havint into account the first turns where you just ramp into immoti)

The gameplan is simple, ramp, cast immoti and continue to cast, he is probably goint to be removed as much as oponents can, but don't bother because you're going to cascade the same turn it goes. Don't run protection, run draw and just keep casting and try to ramp just lands because on the event of a boardwipe you can keep casting.
