I think you may want to go back and re-read my post. You seem to have missed many details in your response.
As I stated, my opponent was using ranged attacks on me, so the bubble around Nico was mostly his support pieces while I had to use my summons to move out and tie up his range pieces. This meant summoning, healing and making Fast every turn to get off the move and attacks. Only things I had at my disposal that coudl reach that far were Kentatori and Shikome. Kents summon natively at a 12crow, and Shikome at 11crow. With the nerfs I had, when the highest I had in my hand was an 11, I needed a 13 to summon the Kent. That meant two sacs of corpses to raise casting by 2, one more sac to summon with only 1 wound, and 1 more to bring him to 5 wounds. Without the nerfs he could have been brought in with nearly full wounds with only 3 corpse.
I was out of points to Take Undead Crowning, nor would it have helped since I couldn't get anyone into my bubble until turn 5. All spare corpses that were generated were well outside Nico's reach, so I could only rely on what Mort and Asura could make. Phillip sand my card draw each turn was just not doing it for the cycling, by turn 5 I pulled no crows and had no stones. this proved to me that nerfing is going to make it that Nico will need to run with full stones again.
As for not summoning 11 and up card summons, with the nerfs I had over half of his summon list was now 11+, so your assessment there was off, and everything left would need a 9 or 10 with nothing in there that was particularly speedy or killy at range. This is what left me with only getting off 4 summons all game, compounding things by making zombies with Maniacal Laughter a waste of time since I had to sac all of them in a turn to counter act the nerfs.
My opponent was smart enough/lucky enough to not have to attack any undead inside Nico's bubble, so They never got to benefit from his pulse flips or he benefit from the card draw, so its easy to counter that bubble and always has been unless you just flood the board with belles. I was unable to summon enough belles because of the situation facing a lot of range attacks, so I got very little chance to Lure. The nerfed summoning would have meant If I had proprieties on belles I would have had not much in good health/Fast to melee with. Also, keep in mind I was now struggling to have enough corpse markers in that situation due to how spread out I had to fight. If I was facing Neverborn or constructs, it would have been the same there as well as much of their pieces don't drop corpses.
My conclusion after that test is that nerfs to Nico's summoning is not needed. Nerfing out card draw off the peons may re-balance him enough by itself.
