This kind of "Meatshield"-Team already exists (even more effective I guess)
Ever tried Idol+Stinker (Sandstorm and double heal), played them together with a Broom since December, its a fearsome combo that has nearly no weakness if played correctly. Only very few teams can stand against them if played correctly, let alone a single pet. Since 5.3 this changed a bit, mostly because of the insane amount of switcher pets and because of this stupid overpowered trihorn
- but it still wins 8 to 10 out of 10
Sure You should bring some time when doing pet battles with this team, think the longest fight I had was around 120 turns ...
(The clue is to not let the broom die, it's your DD and if he does - it will be a long way ...)
PS: And don't play this team if you are in danger of some heart attack, because You may see a miss of this one crucial attack that needs to hit way to often
