But this set of four cards has one more obvious trait going for it: Their spectacular artwork
Pearl-Ear, Imperial Advisor The Pearl-Ear, Imperial Advisor finds a smooth groove in enchantress decks with a substantial cost reduction, whether your auras are for pumping your attackers or enchantment-based removal
It's important to note that Kaito can take advantage of ETB effects like Obscura Interceptor and Baleful Strix
Also XY / Legends Z-A character AZ comes back with AZs Tranquility
You also need to make sure you hit your land drops, either with draw effects (Qiqirn Merchant and Adventurers Airship provide usable bodies as well as draw smoothing) or cards that directly give you lands or mana (World Map, landcyclers, Blitzball)
If you are comfortable with incremental gains and slightly overcosted mana doubling, several of the cards in this list are absolutely worth looking at
