Manamorphose

This card is a staple in EVERY R and/or G colored deck I build, you just can't go wrong with this card; especially at instant speed! I already have like 11, but I need much, much more... It's kinda like Dark Ritual, you can never have enough.

To emphasize the point already made, and give a little of my own feedback, this card is MEAN! It lets you filter two mana FOR FREE and it replaces the card itself. This card may not look like a lot as far as first appearances go, but it is actually a lot better than it might seem at first. Because this card replaces both the mana spent to play it, and the card itself, it's effectively like running a 56 card deck(providing that you run 4 of them), which is an invaluable advantage for aggro (or any other deck, really, but I specifically mention aggro because it's r/g, which happens to be aggro in T2 right now). So, 56 cards? 56 cards provides you with a higher mathematical chance of drawing the cards you want or need, it's like cheating the system, it lets you effectively do something that is illegal at the most basic level of the game. Now, outside of this, the card has many different applications other than this, for example, it lets you get another spell through for storm, for free. Awesome card with a lot of potential.

Two mana for two mana of your choice AND a card?!??! For all I care, it's a free draw a card.

Wow talk about a great cantrip/filter. It's similar to Chromatic sphere/star, but it's free. Combo seems to be the new home - I can see a new 0-land Belcher that might actually run right. Pick up your foils before the Johnny's do.
