For example, Ley Druid targets lands while Fyndhorn Brownie untaps a creature (and, yes, I chose that card as an example because of the sweet art!)
Synchro/Fusion variants aim to go first, gaining field presence with Synchro monsters such as "Blue-Eyes Spirit Dragon", "Blue-Eyes Ultimate Spirit Dragon", and other Dragon Synchro monsters like "Cosmic Blazar Dragon" (summoned using "Crimson Dragon")
From there you can catapult out ahead of your opponents, since your Sol Ring now taps for three mana while Basalt Monolith now creates infinite mana since youre always up one mana every time you untap it
This leads to 0.86 secret rares per box on average
