Breloom or hariyama
Let’s see the pros/cons of them
Brell
Pro
-high attack
-can learn sky uppercut at lvl 36
-can be found early game
Cons
-only it’s attack is good
-4x weakness to flying
-very bad to fit a grass move on it
Yama
Pros
-Very bulky and hard hitting
-Can learn vital throw at lv13, which is very good at that point of the game
-can learn stuff like eq, rock tomb…
-is a early game mon
Cons
-Pitful speed
-if using a belly drum set, it will became vulnerable
-all of his other stats are bad
Overall I would choose Hariyama, it have better coverage moves, acess to bulk up or belly drum,
it have thick fat to protect him for fire and ice moves.
Here’s a set for sumo wrestler:
