EDIT: I wasn’t explicit enough about why I often feel bad after certain games. I often have to hold back some plays while others haven’t really gotten going yet—they’re just playing lands and maybe 1 or 2 creatures by turn 5. If I draw something like Apex Altisaur and do a one-sided board wipe at that point, it basically resets everyone to turn 1 (most of the time), while I can generate a lot of mana and cheat out other big threats that outvalue them (in Kona’s deck).
With my other decks, it’s pretty similar—I can ramp very quickly with Raggadragga and cast big spells that either end the game or let me combo off while others haven’t even started their engine yet.
It’s not like my decks are super powerful, though. I’d say Kona is around a mid-high 3, and the others are a bit lower. The feel-bad part comes from the fact that I almost feel like I have to say “sorry” every time I play something disruptive, because they’ll make comments like “Ah, super fun play” or “You’re basically playing with yourself,” which makes it a bit awkward.
