Seize the Day

So I built a Boros deck, and I think it''s noteworthy. I combo Seize the Day, Zada Hedron Grinder, and Brave the Sands.For those who don''t already know what this does, Zada will copy any instant or sorcery that targets him to every other creature you control. Since Seize the Day targets a creature to untap it, this card will copy to every creature. Thus, if you had 5 creatures, they all untap and you get 5 extra Combat Phases. Brave the Sands is for Vigilance.All are 4 cost or less so fairly quick to get going. It''s a sure win if you pull it off. What''s more is Seize the Day has Flashback so you can actually cast it again after taking your X combat phases, to take X more again.Without vigilance, your creatures would only be good for the first combat. After that they''d stay tapped. Thus vigilance is key. Since you played the copies all in the same phase, after one phase ends your guys are still tapped come the next one without it.It''s a really fun combo and super cheap to build a deck around, since Seize the Day is the only card mentioned worth more than a dollar. Definitely worth adding to your decks.

You don't draw an extra card. it creates an extra combat and an extra main phase. you draw your card for your turn during the draw phase at the beginning of each turn.
I'm thinking exalted creatures. the exalted text says that the creature gets +1/+1 until the end of turn. and all of these combat phases happen during the same turn. so let's say you have a battlegrace angel, a stoic angel, and a rafiq. attack with the battlegrace angel: that's 16 life and 16 damage (rafiq gives double strike). then play seize the day. that's 22 more life and 22 more damage. if you can flash it back in the same turn, that's 28 more damage and 28 more life. unless your opponent has a similar deck (or some other kind of deck that gains massive amounts of life) they're dead. drop a loxodon warhammer onto your stoic angel (lifelink stacks) and you just gained over 70 life.

this card is awesome two combat phases and u get to draw that card in the main phase it even has that flashback

Personally, I think this is stronger than Relentless. I envision a W/R deck with lots of exalted winning on turn 4 with this (exalted lasts until end of the turn, but triggers during both combat phases; that means double exalted for the second attack).

Who needs relentless assault? You never get to attack with more than one big creature anyway, and Seize the Day requires only one red mana. Thus, you can use it�s flashback ability for 2R only! Kick ass!!

Good Card, but relentless asualt is way, way better.
