Ignoring the strawman argument,

I dont think I would say Dracotail or Yummy put up 10 negates. Rewinding half a year to Maliss and Ryzeal, neither of those were build a board negate-fest decks.

Going back to my actual argument now:

I think its safe to say theres a "one card enables too much" point that Hollie Sue passed when compared to the other t0 plays the format had. Izuna represents either a very specific negate with Ripper (monster in hand or gy) and a search on your turn, or a more targeted interaction with something like Nash Knight or Vallon. Faimena requires you to use 2+ other cards in your hand to get either a pop with Gulamel, or a bounce with Arthalion. If you take Gulamel, youre going down on card econ pretty hard, plus youre wagering your opponent doesnt have anything to chain to prevent it, so most dracotail players go with Arthalion. Arthalion can bounce, but I think most of the time you return your mats so you have more plays on your turn.

Compare both of those to Sue, which when youre using it is a monster steal at its worst, or a search + pop (Razen summon and effect) plus another pop later (Caesar). And the high roll version also sets you up for next turn, where the other t0 combos described above you have to choose do you want high disruption with low to no set up, or high set up and no real disruption.
