**Edit: Due to the increased popularity and demand for misprints off-centered cards are now sought out by some collectors
Its been around for years, with a client on Windows, Mac, iOS, and Google Play (although the mobile app is objectively terrible)
These notably feature the new dual-ink cards being introduced in the set
Cards that discard Energy like Team Rocket Grunt and Guzzlord ex can put Lugia ex on the back foot if they're able to get successful flips
(To mill a card, put the top card of your library into your graveyard.) Choose a Background (You can have a Background as a second commander.) To resolve the activated ability, first mill a card for the first opponent in turn order
The combos for the kitty are all over the place, the sort of thing you can stumble into accidentally, especially when stuff like Mox Opal/Amber is involved
