Here is my combo multiresource deck. I wonder if the combo inside it is overpowered, but I don't have enough time to test it throughfully in ranked. So, dunno if it is competitive or just fun :)
The description format is stolen from this great deck's description by Atmaz.
= Key Scroll (Fundamental to the deck operating correctly)
This is a key creature of the deck, that is needed for the combo. You'd like to start with one, or draw her soon enough. Good thing: the deck have both Eye of Eagle, Somata Shift and not a lot of other creatures, so it shouldn't be that of a problem.
If you have only one Mystic, you'd want to protect her at any cost.
The second part of the combo. Guess what would happen when you trigger the “Draw Enchantment” on Mystic that heve Veil on her? Yep. You can draw as many scrolls as Mystic has health. And after you'd draw all those cards, you still woul be able to attack this round. Cool, huh.
You'd want to start with Veil in your hand, so it would be ok to mulligan in an attempt to get this even if you'd lose a Mystic.
As Veil have replenish, it plays nicely with a lot of other enchantments.
The third part of the combo. When a Mystic with the Bloodboil draws an enchantment, she gets +2 attack. Along with Veil and a lot of health you could ramp up the attack to the redicolous heights.
Also, the Bloodboil is very important as it have replenish and is of the main deck's color — growth. If you would have both it and Veil in a starting hand, you would want to save them, as this would allow you not to sacrifice for order, but just cast Bloodboil and then Veil.
The last part of the combo. When you would have a lot of attack on Mystic, it would be useless without the relentless. This enchantment provides exactly that.
It can be sometimes not that easy to cast it, as the Energy is the third resource you'd like to sacrifuce for, but it is ok to cast it later than sooner and other enchantments with replenish would make it easier.
Most of those scrolls are there to keep you from losing your Mystic or idols until you'll trigger the combo. I guess there are a lot of possible variants of this deck, where those scrolls could be swapped for some other, making new combos or helping existing key scrolls in some ways.
Asks your opponents to use their removals on them, protects Mystics, does some initial damage to idols.
In some cases could be a treat on himself, when buffed, but you always should place them in front of Mystics, as Mystics are VIP there.
The only purpose of it is to protect your Mystic or idols.
The same as Rat King, provides nice protection that can take a few hits and then, maybe, burst out with more protection.
Just one, just in case. Good for Braves, good for Mystic if in some strange occasion you wouldn't have Bloodboil, or just extra four damage for rats or nogs, if you'd need it.
Druid Burial Ground:
Protection and extra health regen for Mystics if you wouldn't have any other healing stuff for some reason.
All the same stuff: extra protection, extra health. Nice after Frost Gale.
I like how this deck plays, other than the key combo, there are a lot of scrolls that interact in nice ways.
One of the things I noticed while playing this deck is that you should draw cards to the maximum from the Mystic, but not until she loses the ward from the Verdant Veil, or becomes too beaten up. This is because the less enchantments are there left in the deck, the more other useful stuff you would get to protect your Mystic.
Also, don't stop on one mystic: keep the second Bloodboil and Vengeance Veil, so you could then spawn a second one and make her as powerful as the first one. This is just a matter of a one or two rounds, so if your opponent would somehow manage to kill your first baffed up Mystic, there are great chances to redo the combo using those enchantments you have saved in your hand.
