Aesi, Tyrant of Gyre Strait is a big beast that would cost you around $10 on its own, while Giggling Skitterspike and Ashaya, Soul of the Wild arent far behind
This would be a good enough effect on its own, but take note: Swords to Plowshares is an instant , meaning that it can also be used offensively to interrupt your opponents key plays
Also consider that M10 rotates out of standard with Shards of Alara block this fall, so you have approximately 3 months of overlap with M10 and M11 which may spell some very interesting changes with your local metagame
As well as the physical Pokmon Trading Card Game, you can play the Pokmon card game digitally using the Pokmon TCG Live app
My tip is pick Pokmon of one type. So, say, Electric, or Dark, or Psychic
