There is almost no content on Legacy! So here’s possibly the most fun deck in format, and certainly tier 1 as well.
Here’s Simon Narode’s build:
Use Weavile’s attack ‘Vilify’ until you take all 6 prizes.
Discard as many pokemon as you like from your hand. This attack does 30 times the number of pokemon discarded.
Use Exeggcute’s propagation to set up quickly and effectively by eliminating the downsides of Junk Arm, Dowsing Machine, and Ultra Ball.
Stream Weaviles using your 2 copies of super rod and 4 copies of Dark patch.
Junk hunt when/if you need to get back resources such as J-arm and Super rod.
When building your own version of Weavile, feel free to edit the list however you like. The list provided has been testing extremely well, however.
NOTES: Through about 20 games with this, I would include a 2nd catcher and a town map.
Town map is for when you prize Exeggcutes and need to find them.
Catcher is for prize trade and a 2nd would greatly improve the Blastoise and TDK matchups.
