I'm glad you like it :) It should be okay to have more Pokemon in party but only use 3 of them in battle.
My idea with Delibird was that it comes later in the game, so you should have enough TM/HM to teach it and because of other Pokemon and rules, you don't even have to use it. And yes, older attacks we meant as gen 1, 2 and 3
Cool cool, gen 3 was one of my favorites along with gen 2. They released one of my favorite moves sheer cold 👀. Love it because at absolute zero nothing exist, since the wave function would collapse. It fits the ohko meaning fine.
And ahh okay, wanted to ask because I didn't want to not use delibird and not tell you since you made the team. Any other ice type that would fit this theme you think? If not I'll use delibird
