Dragon synergy with aoe damaging spells and abilities good against other control solid against aggro can still get rushed down with poor draw and aggro god start.
Will go into more detail with certain decks later.
Try to get 1-4 drops in your starting hand especially Hellfire and if its warrior play like its pirate. It's easier to draw good cards later to play against taunt then top deck early to counter aggro.
You have a lot of single target removal but don't go throwing it around, if you can kill a minion with minions and other spells other then aoe spells of course do that and use single target removal as a last resort. If you feel you need to heal just heal use Drain Life before Siphon Soul if possible.
Just control the board plenty of clear and high value minions.
Pretty simple, know the deck and play around the combo. For example exodia mage try to deal damage as quickly as possible to prevent them from drawing the infinite fireball combo.
A more complete guide will be done at a later date with match ups and how to play them and replacements and so on.
Any comments or opinions on the deck are appreciated and will be answered to the best of my time and ability!
