The base level for cards like Rashmi, Eternities Crafter, Cosmic Crucible, and Arcane Bombardment is that you cast a spell during your turn, trigger these permanents, then pass and wait for your next turn to do it again
It actually reminds me of how Magic used to be
Aetherspouts is strictly worse than Cyclonic Rift, but is still a potent defensive card, as you simply cant block much
Control decks are usually much lighter on wincons and board presence, with more emphasis on interaction through counterspells, board wipes, and flash threats
Their silver border and acorn stamp show that they cannot be used in any legal play
Each pack contains 6 cards with different rarities , from Chief to Common, Uncommon, Rare, Super Rare and Secret Rare
