Aluren

As powerful as this card is I'm surprised it's not banned or restricted in any format... Though one might say it's balanced BECAUSE it affects all players, but I dunno... Too many combos can come from this, Especially with Cloudstone Curio going around these days.

This card is simply amazing - so many crazy things you can do with it!

Green & Blue (mentioned above)
Man'o'War + Brain Freeze = insane burst mill, possibly 2nd turn

Green & Red (mentioned above)
Grinning Ignus + Banefire = Absolutely insane amount of red mana, and a hideous spell.
If you want to use this trick in multiplayer, just Side Board a few Radiates - you'll have the mana for them.

Mono-Green (also mentioned above)
The most classic trick is, of course, +Recycle +Elves for a deck that flushes the field in no-time flat.
Concordant Crossroads cracks this wide open with mana elves. I like to toss in Symbiotic Deployment or Fastbond.

Black & Green
Eternal Witness + Altar of Dementia + Leyline of the Void = Opponent's decks vanish as quick as 2nd turn.
Benefit to this method, is that they'll never have a graveyard. Stops re-shuffling and Eldrazi dead in their tracks.

Black & Green
Shambling Shell + Gleancrawler + Savra (optionally + Bloodbond March) = You're the only one with creatures.
If you're game for high mana costs, throw in "It That Betrays" and every creature to breathe will be yours.

Basically breaking this card is a simple formula:
Cheap creature that can return to your hand somehow, Aluren, third card for the kill.
Try looking over your cheaper creatures, and you might be surprised what you can do with this.

Great card. works great with Fleetfoot Panther and Soul Warden for infinate life.

opps, I mean Grinning Ignus

aluren+burning ignus+banefire

Yes this card is great but the best combo ive seen with this is this - Have aluren goblin bombardment and two junk divers out - sacrifice a junk diver deal 1 damage then sacrifice the other junk diver to bring the junk diver back into ur hand then put it right back out and keep doing this and all ur enemys will instantly die

nonononono....
better combo's can be made with aluren... the card is TOTALLY broken... its the best ever..... just get it on it on the table.. play Man-o'-war en target itself... then do that about a 10000 times and then just use Brain Freeze... when its his turn.. he can't pick up a card an he will be killed..

i have been playin since tempest came out and realized the nastiness of this card from the start. just recently, i made a deck with this that allows for massive numbers of creatures, massive creatures, and, if u play it right, massive life. one nice combo is as follows: (this is my deck)

3x Aluren
3x Recycle
3x Quirion Dryad
3x Chlorophant
3x krosan Restorer
3x Anurid Scavenger
3x Feldons Cane
3x Manowar
3x Counterspell
3x Rights of Refusal
3x Spontaneous generation

What can I say....this is a great card. It makes a neat combo with Recycle [draw a card when you play a card], allowing you to scroll through your deck and play lots of creature! It also makes a neat combo with Kavu Monarch and Horned Kavu. Attack with the Monarch, then cast the Horned Kavu as an instant, return itself to your hand, and play again for a trampler of titanic proportions!

This is an overlooked yet quite powerful card. Any elves deck or weenie deck should have 1 or more of these in it, coupled with any card that allows more draws it can be quite lethal. I am currently making an elves deck and know this card will be useful!
