When they Are Summoned, (usually they don't trigger)

To answer to your other post, yeah, they used to require  only two materials (the second random), however, they sometimes they require one material only, or both random materials (with different names), the combinations of their Levels/Ranks will let them gain stage equal to the materials' levels/Ranks, otherwise, if the Evolute Monster requires only One Material, its stage is Doubled Equal to its Levels (as long as it doesn't exceed Stage 13)

Example:

Level 2 + Level 8 = Stage 10

Rank 1 + Rank 6= Stage 7

and so on.

And Yes, LHK, Counter Cleaner is a big Threat to these cards, especially when you combine it with Breakthrough Skill makes Evolute Monster Exposed to any other card effects/Attack Target.
