There's definitely a compromise with going 2nd compared to classic Infernoid builds, but its not completely helpless since you can still use TCBOO/rivalry/gozen to break boards. Multiple s/t negates are tough and probably will lose to, but luckily monster disruptions are more common these days. I did not see much Dragon Link and Drytron in my Diamond climb (I went 1st in the few times I ran into them ). I played around with going 2nd cards like evenly, kaijus, lava golem but ultimately settled for the Lilith package and Demise for consistency.

Unfortunately I keep forgetting to save the interesting duels I've had during the climb, but I made some of the recent duels public. I'll try to save replays more often next time.

Since the deck runs extravagance, you need pretty much everything there - the only flex spots in the extra deck are relinquished, barricadeborg (and maybe the 2nd copy of gravity controller, but its very good to have when Tierra gets negated). Relinquished and barricadeborg could be replaced with 2nd copies of Duelittle and Hiita
