Lets say you start your deck with a good starter that helps you speed up your set up
Whispers of the Muse (T1, Ext, S, Block) A favorite in "Turbo Xerox" (a blue deck which used minimal land but a ton of cantrips to thin out the deck), Counter-Phoenix (Shard Phoenix + Forbid) and Tradewind-Awakening (put Awakening on the stack, tap all your lands for mana, untap all your lands), Whispers has what might seem like a hefty price to pay for one card but you get to do it turn after turn after turn
Surrak is a great Warrior to give double strike to, and even on an empty battlefield, Grotesque Mutation makes him big enough to attack with haste (and lifelink!)
It is suitable for deck building, gameplay, and expanding a Magic The Gathering collection
Price Buying all the cards in the Blue/Purple Luffy deck costs at least 33,970 JPY (~US$230)
These are generally blue-green decks and a hyper-specific subcategory of control decks
