Quote from ElectricEye »Birds of Paradise and Noble Hierarch have been the best mana creatures in modern since the format's inception. Deathrite, appearing quickly onto the scene but disappearing soon afterwards, briefly took the first place slot. Third place goes to Arbor Elf.
I believe Modern Horizons would be a perfect place to print new mana creatures that could compete for power level with Birds and Hierarch. These are the type of cards that are too good for standard - where they hesitated to even print Llanowar Elves - but are perfectly acceptable in modern and legacy.
I can't wait to see what they come up with.
