- Minor Refraction is a unit-upgrade that makes the units Size 1. Does not add or remove a size, it makes it exactly size 1. So all your mega-size units becomes tiny, and fit everywhere.

- you can use cards that move units between floors even if the unit is on the top/bottom floor. The effect applies, only the unit does not move

- you can use your cards on the enemy (like moving them between floors, positions you occasionaly want to)

- you can harm your own units (sometimtes you want it to create space - looking at imps)

- when things split, the spaned units keep the original's upgrades. The candle-race's 4 size wax giant deserves the +15/+25/+1 size upgrade for this

- you actualy can have more units than space on a floor by moving the units between floors, units spawning more units, changing size of the floor, and all the other crazy things. I think I once had a dozen unit on my side, and 6-8 on the enemy side. That was fun. This causes no trouble at all.

- the never tell you this, but Morselmaker summons the morsels AHEAD of him.

Handy topic.

- when faced by enemies with Incant (gain a bonus when a spell is cast on their floor), the problem can be avoided for spells that create units or items (like morsels): cast it on another floor, then change floors and drop your morsels

- Incant triggers after the spell resolves, so if the unit gains armor from Incant, a damage spell is resolved before the armor is applied There is, however, a hard limit of 7 units on your side, regardless of how many pips the floor has. The game warns you when it first happens, and states that further moves and splits will fail because of this. So I suspect you must have miscounted the dozen on your side :)
