But you don't use Smeargle to use tackle. You really are being stupid. You obviously don't know how good Smeargle is. Magikarp has 3 moves so it is not better than Smeargle. All Smeargle needs is it's decent speed stat and it can ignore ever other stat as it's main purpose it so pass belly drums and put a pokemon to sleep which only need it to be faster than the pokemon it is up against. It could have a base of 1 in all stats except speed (and maybe HP as you need divisible by 4) and it would be better than a Magikarp. Smeargle is one of the best baton passers and has been since GSC and you can bring it on so much, try encoring a shadow ball then bringing him in or bringing him in on a CSpecs shadow ball. Even encoring a stat-up move.
And if we wanna look at his attack stat, lets use belly drum explosion as that would be one of the only cases where you would attack with smeargle. 3
Jolly Smeargle (139 Attack) vs. Bold Cloyster (504 Def, 304 HP [both max]):
Belly Drum Explosion (STAB + 500 BP + 4x damage): 197.70 - 232.57 %
Adamant Magikarp (130 Attack) vs. Bold Cloyster (504 Def, 304 HP [both max]):
Tackle (35 BP): 3.95 - 4.61 % (12 - 14 HP damage)
Oh you must be right, magikarp is better.
And one more calculation:
Jolly Smeargle (139 Attack) vs. Bold Golem (394 Def, 364 HP [both max]):
Belly Drum Explosion (STAB + 500 BP + 2x damage): 105.22 - 123.90 %
It even OHKO's Golem. Obviously if you were to use a belly drummed explosion you're not gonna pull it out on an Aggron or a Bastiodon, which don't exist in OU anyway, which is where I think Smeargle is hanging out, possibly BL and those guys are UU anyway.
Smeargle is one of the MOST useful pokemon out there, how can you not get more useful than whatever move you want?
Edit: the struggle battle. IIRC struggle gives no STAB.
We'll give both Magikarp and Smeargle: Bold Nature, 252 Attack, 252 Defense, 4 HP.
Magikarp's Struggle against Smeargle:
9.29 - 11.51 %
Smeargle's Struggle against Smeargle:
12.64 - 14.84 %
Smeargle also wins the struggle war. How in the world does Magikarp beat Smeargle with Tackle vs. Tackle?
You want numbers, I gave you numbers.
