I love tempo-shifting cards like this, and the fact that this can be a ritual and a wrath in some decks makes it really good value indeed
You can rapidly bring out large characters like "OP06-114 Wyper" and "OP08-099 Kalgara." "OP06-114 Wyper" can activate an [On Play] effect if you have "OP05-117 Upper Yard," but its 7000 power is also very high for 5 cost
Otherwise, put a +1/+1 counter on this creature, then put the card back or put it into your graveyard.) Creature - Scout Merfolk Sinuous Benthisaur When this creature enters, look at the top X cards of your library, where X is the number of Caves you control plus the number of Cave cards in your graveyard
So if you cast something on turn one that can en-counter it, then you can have six mana on the third turn
Whatever, its not important
As far as your basic cyclers go I really like either two colourless mana or one coloured mana
