Fun fun. The side deck can be whatever you want but in playtesting i've found that dragonrulers and dragonmaids actually meld pretty well with amorphage. Maids offer good tribute fodder, rulers can help make odd eyes absolute which you can link away to spheres to pull out vortex to use already expended amorphages to fuel its omninegate and pull whatever one you need out with spheres. Laundry is actually pretty clutch in the deck, milling 3 when 37/40 cards can be used in the gy in some capacity is actually pretty huge, and by extension we get to run nudyarl which has a quick effect to either just put something irrelevant back just to get it into the gy to go into lady's or actually function as disruption to spin something away from the opponents gy. Nurse is probably the weakest link as it does nothing by itself as an opening play but is such an amazing extender (as well as ernus, quick effect SS of a little maid to further lean into making plays on the opponents turn) that it's hard not to include her. Besides she helps round the attribute soread out, though since everything is a dragon attirbutes hardly matter. The attribute spread is a very nice 3/3/6/6/6/6 Light/Dark/Earth/Water/Fire/Wind respectively. Although, If I'm being honest, my first cuts for side boarding are always 2 hospitality, 2 tidying, and 2 changeover, and as far as the creatures go, are laundry and nudyarl, nurse and earnus, and 1 copy of chamber make for 13 total cards cut to swap in every single amorphage. As far as extra deck goes, the swaps are 1 sheou and 1 eclipse. Sometimes you might want to keep both copies of spirit since just linking to it and then going into spheres with some other expendible can put 1 more additional dragon body into the gy which can mean the difference between being able to go into disaster or not.
