are there any infinite combos with {Radha, Heir to Keld}? For edh and or TL
Way too many to count.
I think what Glowack is trying to say, is that any combo with mana elves will work with your commander...
I would suggest {firebreathing} and {skyshroud elf} to use if you trigger a infinite {G} combo.
Wait, skyshroud is {R}{G}{W}. Never mind me.
