Today's CotD is Rayquaza & Deoxys Legend from UD, one of the more interesting and (imo) useful Legend cards out there. Statwise, 140 HP is about the minimum for a Legend (notably this is also a dual type Pokemon, being :colorless:
sychic
, x2 Weakness to :colorless: and
sychic: is bad (stuff like Garchomp C Lv X OHKOs it instantly, as well as Gengar, both being 2 of the more popular decks), and :colorless::colorless::colorless: to Retreat is expensive. Space Virus is a great Poke-Body, giving you an extra prize if R/D Legend KOs something. That being said though, Oozone Buster is a tad trickey to pull off; :fire::fire::lightning::colorless: is a nasty combo of Energy to get onto him, and though it deals a powerful 150 damage (enough to KO almost any Pokemon), you have to discard all :fire: Energy on R/D Legend. Shame most of the more effective ways of retaining :fire: Energy went out the door in the format change...Typhlosion Prime can be used, but the 1 damage counter you take from his Poke-Power is icky.
Modified - 6/10 (Maybe if there were a more efficient way of getting the Energy out, it would be a lot more useful. However, that all died out last format, leaving R/D Legend a tricky one to use at best, and it has a lot of unfortunate Weaknesses)
Limited - 2/10 (Good luck not only getting both the proper parts, but then actually getting them in play. The Energy requirement is nasty as well, really the only good part about this Pokemon here is that with 2 attacks, you win...which of course in the time it takes to do those 2 attacks, you could have found a better way to win with other Pokemon or your opponent already has taken their 4 prizes)
Unlimited - 1/10 (Not much use here, ER/SER absolutely destroys this card's ability to attack, plus the Weaknesses aren't that good either)
