Im just gonna throw some theory at you all if im wrong just disregard my comment.
Battle compressor in theory should be really good for this deck. We all know letter is great, but also pokemon like eggecute plf you can now quickly dump them with battle compressor to create quick superior e. retrieval at 0 cost. Also, ultra ball is still great with this. Along with dowsing.
Ive also, seen people debating about support in my personal opinion the best support line in this deck is
1x jaraichi ex
1x colress (can be dropped)
3x vs seeker
2x skyla (vs seeker is more efficient now.)
I dont feel like you need more or less than this.
As for blastoise lines
4-1-4 is most effective (if you feel that you can dodge the toad drop it to a 4-0-4 line.) Playing more wartortile slows the deck immensely.
I think blastoise would benefit from 1x toad in their lists. As we can use the second attack as well. But there are much more efficient water attackers. Keldeo ex for example.
If you want manetric ex and mega manetric the deck wont have any room for more than a 2-1 line with 1 spirit link. This can be really good in the right meta. Dropping 1x s.e.r can help accomidate this.
Please dont go less than 4x rare candy. If you want to actually play a blastoise deck. Imo you can play less but it defeats the purpose of t2 blastoise.
I don’t think black kyrem ex is viable anymore due to mega evolutions exceding 200hp but overrun on manetric ex can help soften them up a bit. But dedicating 2-3 spots to this pokemon i dont think is the answer.
Pokemon i would consider for the deck would be.
- suicune safeguard.
- mewtwo ex hits for weakness on alot of new fighting pokemon + phycic wars.
- eggecute propagation ability. 1-2 with battle compressor.
- keldeo ex 2x keldeo
- manetric ex and m manetric. 2x -1 line. With 1x spirit link.
- jaraichi ex at 1.
- black kyurem ex at 1x.
Please reply if you have any questions.
