I got Growing Rites as well (Twice actually) and was super super excited about it. Unfortunately I already experimented with it twice but didn’t see it actually put creature cards into graveyard but exile them instead. I wonder if I should post a bug on this, but I’d like someone else to confirm it too (try it only with Embalmers/Eternalize creatures and notice no activation gems appear after its usage).
Captain Lannery Storm has already been really fun to play around with, just wish Trove of Temptation comboed with her instead of making a treasure after combat.
Also got a Mavren Fein, but my word the hoops you have to jump through just to get a 1/1 lifelink token are pretty absurd. So far he’s just been a cheap creature, I’ve only managed to get 1 or 2 tokens out of him.
Don’t know about best pull, but I opened up my 1st premium pack and got a total of 4 rares!
Conqueror’s Galleon
Deadeye Tracker
Fathom Fleet Captain
Goring Ceratops
Edit: Wow. Second premium pack two mythics, Dire Fleet Ravager and Regisaur Alpha. Bonus rare Treasure Map. Nice.
Edit 2: YEEEEEESSSS! RIVER’S REBUKE AS BONUS RARE IN THIRD AND FINAL PREMIUM PACK! Wooooot! Plus got Ixalan’s Binding and Fell Flagship.
