Sound like a "all the cool pokemons i can get in my deck" deck
And lets see Jirachi is mostly used for 2 Staged pokemon evolved with rare candies, if you devolve a Donphan it will evolve in you opponent's next turn.
Do me a favor choose a main attacker or two, and some techs (not 1 milion).
Well...
Ho-oh is not a really great card.
I can say Ursaring is better.
- 2-2 Ho-oh Legend
+ 1-0-1 Nidoking RR
+ 1-0-1 Exploud SV
This might help, nidoking will add 2 damage couters everytime your foe's active damage attacks you, and exploud will take out your ursaring's fighting...
