Talk:Fifth Omni Dragon Lord, Crimson Drum/@comment-25004901-20151023034257/@comment-24965906-20151023072822

I can give you a reason why that's fundamentally not a good option.

Both those monsters are Size 2. Unless you use Ein and Dragon Throne (in which case you could only use one of Omni Crimson Drum due to the Omni Lord Keyword), it's impossible.
