Today's CotD and the first for March this year is Relicanth from CL...another sorta tossed in the set Pokemon. Statwise 80 HP is nice for a Basic, x2 Weakness to :grass: is eh, no Resistance is common, and :colorless::colorless: to Retreat is a bit pricey. Prehistoric Wisdom is ok, drawing 3 is nice for :colorless:, but having to give up a card in your hand to be sent to the Lost Zone beforehand sucks, unless your deck is built around having something in the Lost Zone. Imo better Pokemon to use for this role instead if you're not using the Lost Zone...Granite Head sucks for :water::colorless::colorless: for a very cruddy 30 and 30 damage reduction on Relicanth during the opponent's next turn.
Modified - 3/10 (No real use unless you need a quick way to drop cards into the Lost Zone, then it becomes a decent card)
Limited - 9/10 (Lost Zone is still a bit eh, but the draw 3 effect is great, you should be able to come up with something to sacrifice to the Lost Zone to get 3 more cards here. 2nd attack is still horrible though)
Unlimited - 1/10 (No use here, just all around bad)
