You can currently get your hands on Bloomburrow boosters and decks at Amazon , but beware prices are all over the place
Simic provides way better tools for this style of play: better 1-drops with Blue's unblockable beaters (Gudul Lurker) and Green's mana dorks (Llanowar Elves), better removal with Blue's creature removal (Pongify) and Green's disenchants (Nature's Claim), countermagic which is just busted (Fierce Guardianship), and better finishers thanks to extra turns (Notorious Throng)
But there are one-off scenarios where we may want to protect our creatures and Grand Crescendo can help with that
Undead Alchemist converts milled creatures into your own creatures, which themselves can attack for more mill
The Aristocrats/combat combination that we have in the deck can work, in fact Ive done it pretty spectacularly with a Garna, Bloodfist of KeldGarna, Bloodfist of Keld deck
Q: Can I receive these sale prices if purchasing these same items at Star City Comics & Games physical location
