People keep saying it's good with venusaur, but I don't think anyone realises just how good this is.
If exeggutor has 3 grass energy on it (minimum for attack) and venusaur is in play that is 6 coin flips. The probabilities are as follows
- 0 heads: 0 damage: 1.56%
- 1 heads: 80 damage: 9.38%
- 2 heads: 160 damage: 23.44%
- 3 heads: 240 damage: 31.25%
- 4 heads: 320 damage: 23.44%
- 5 heads: 400 damage: 9.38%
- 6 heads: 480 damage: 1.56%
Now we can basically combine all results above 3 heads, because with choice band 240 damage is doing 270 to stage2 gx's meaning all those results are one-shotting everything in the game. So the total percent to
one-shot any pokemon is 65.63%. That's actually insane and then the 160(190) damage for 23.44% is not even a bad attack for 3 energy, 160 for 3 energy is a good attack that kills things like drampa and tauros with choice band. That means only ~11% of the time will this attack be bad. Then if you throw a victini on your bench you have 2 chances of that. 2 chances at getting at least 89% (66% if you're greedy).
And that's just assuming 3 energy. With 4 energy the chance to one shot goes up to 85.55%, 96% to do more than 160 damage. And with 5 energy it's a basically guaranteed one shot, though thats a bit too much energy to risk losing.
Now if you don't need choice band because you aren't fighting metagross, you can use wishful baton to pass the 3 energy to your next exeggutor so you don't even need to set up again. If you do need to set up fomantis/lurantis might be a good inclusion as well.
Obviously this deck sucks against garbotoxin so definitely 3, possibly 4 field blower is a must. Other than that if you can find an easy way to get venusaur up while accelerating energy to the exeggutors, this deck is going to be actually really good.
