I'll allow that card as a semi-limited. That okay with you?

Sure. It's a tech card for modulations.

The idea is that if the levels are close enough, you can bring them closer together for an xyz, or further apart depending on what you increase or decrease. You can also stop special summons based on levels (however not ranks) by excluding levels outside the inside the bounds. But if you are trying to cover too broad of a range, both monsters get destroyed :I
