My version of the green-white enchantment deck.

I gave it the aggro tag, but it can also be played as a combo deck (kind of).

It's a pretty fast paced, efficiënt top tier deck that's perfect for climbing ranked in BO1.

The deck is pretty good in BO3 as well, but since it's aggro it'll always have an edge in BO1.

Objective

There are two ways to play this deck.

You can simply play cheap creatures on curve, buff them with enchantments and attack - aggro style.

But when you have a Paradise Druid and a Setessan Champion or a Season of Growth on the board, you can also play it like a combo deck. 
Just don't attack with your Paradise Druid so it keeps its hexproof, buff it up and keep drawing with Setessan Champion or Season of Growth. It's pretty easy to create a giant creature and OTK your opponent. 

The aggro playstyle is more reliable though.

Card Purpose

• Season of Growth
  I used to play a Bronzehide Lion, but sometimes I wouldn't draw a Setessan Champion which means I would draw dead.
  So I added Season of Growth and it's amazing. It's an enchantment so it procs Setessan Champion and everytime you cast an enchantment on a creature you draw a card. 
  
  
• Alseid of Life's Bounty
  Cheap enchantment creature. Keep in mind that you can give another creature protection! 
  
  
• Paradise Druid
  This card is included because it fixes your mana of course, but it also has hexproof which makes it an incredible creature to put enchantments on.
  
  
• Transcendent Envoy
  It makes your aura's cheaper which is useful, but it's also a flying (enchantment!) creature. This makes it a great target for enchantments because in a lot of cases your opponent won't be able to block this.
  
  
• Banishing Light
  This is for those few games when you can't get through your opponent's defenses. It's gets rid of pretty much anything in your way.
  Super powerful card. And it's an echantment so it procs your Setessan Champion! 
  
  
• Setessan Champion
  Does this need explaining? The whole deck is about this card. It's absolutely nuts. You can't play this deck without Setessan Champion.
  I mean you can, but why would you want to lose?

Tips

• You always want a Setessan Champion or a Season of Growth in your opening hand. This deck is very draw dependand, so you need at least one of these two to get going.
  
  
• Paradise Druid is probably the best target for enchantments because it has hexproof.
  
  
• You'll probably want to spread out your enchantments though so that your opponent has a harder time deciding which one of your creatures to destroy.
  
  
• Banishing Light 
  I often see that people forget this, but: you can remove the opponent's Banishing Light with your Banishing Light!
  
  
• Having 2 Setessan Champions on the board usually isn't a good thing. It's too much card draw actually and if your opponent has a sweeper, you suddenly lose 2 copies of your best card.

Sideboard

• Destiny Spinner
  Great enchantment creature that you'll want to play against counter decks to protect your enchantments. 
  I would replace Transcendent Envoy with this card.
  
  
• Conclave Tribunal 
  This is basically another Banishing Light, but a little worse. Sometimes you need it though.
  
  
• Devout Decree
  Black is popular right now, so obviously this card is good. Especially versus cats it's very useful (if you can playing without them having an untapped oven of course).
  
  
• Revoke Existence
  Since there are a lot of decks with enchantments these days...
  
  
• Elspeth Conquers Death
  It's a really strong enchantment that's too slow to put in the main deck, but it's great against control. 
  And don't forget you can bring back a Setessan Champion for example from the graveyard!

Usually I don't like playing aggro decks, but the way this deck plays just feels so nice.

All the cards have so much synergy with each other, you'll pretty much never have a bad hand, and there are a lot of fun combo's possible. 

Have fun!

Cheers.
