I think thats the greatest advantage in the game, to combo dragons and neutrals with any deck.
Delwyn (max lvl) -> +1 Magic dmg is just simple and effective since there are many good dragon cards that combos well.
Daria (max lvl) -> Also a simple +1 melee attack, these two already give a great variety of possibilities.
Naga Assassin (max lvl) -> Its just too good of a deal, 2 mana for swiftness. Its a fast card,can attack first many times, if evades gives return fire. Still has 5hp.
Dhampir Infiltrator (max lvl) -> This card can cause lots of damage with Daria and double attacking back line, I use a lot. 2x cripple its a plus, and affliction can also prevent triage.
Djinn Chwala (max lvl) -> Good status, can do high dmg with enrage and throns on 1x1.
Lightning Dragon (max lvl) -> Its very good is diamond league where it gets blast ranged attack with piercing. Very fast, can be one of first hit and already give a stun. Good evader with flying to gamble.
Gold Dragon (max lvl) -> I think this is the MVP in the team. I use a lot! For me is the best deal that much dmg with blast and still has heal, can survive a lot, but still is better to protect it, like a chess's queen. Magic return can be helpfull.
Black Dragon (max lvl) -> Good in some situations since it has low hp, even with his strenght, but a good support, has slow. I like it for equalizer rules or blast. Better if you are able to stack good hp with life leech.
Red Dragon (max lvl) -> Good in melee only battles, even more with can attack from anywhere is melee mayhem, opportunity, super sneak, doing magic dmg together. His heal is able to move him to any position. Has low speed, so I would also consider in reverse speed.
Void Dragon (max lvl) -> Thats one the best low mana tankers for me, has good hp with void. Can evade a lot magic dmg with Phase. If gets enrage miss rates will increase with the speed. Crazy good card, wins great value.
The Vigilator (max lvl) -> This as its name intels, is camping expecting high mana battles where can attack from anywhere. Does lots of dmg in this case, 1 ranged + 3 melee x 2twice + Thorns + Poison. Destructive.
Dragon Jumper (lvl 1) -> I don't use much because of his lvl and low hp, mas attack fast and do good dmg and opportunity, good card.
Diamond Dragon (lvl 1) -> Good in some situations like void shield, in this case can keep slow active for a long time.
Chaos Dragon (max lvl) -> I can't play without this card for high mana battles, I would say its the 2nd best in my deck only because of cost. Massive dmg in mid formation, its rng and you can distribute dmg also. But blind is also a great support. A good back liner with lots of shield and hp, or as a secondary tanker even though you want him doing the max dmg for the max amount of time.
Desert Dragon (max lvl) -> I like to use in back line to give retaliate in some sneak, killing it with piercing and activating trample, it can win a game this way, but its a gamble since is slow. An interesting card.
Lord Arianthus (max lvl) -> A good tanker against a mixed deck. Void + Magic reflect. Try to get it backed with amplify. Or shield + Thorns against melees.
Prismatic Energy (lvl 5) -> Good secondary tanker with void to take magic blast dmg and reflect it. (Again amplify it)
Cripple Ozze (lvl 1) -> 1 mana for 1 slow bait seens a fair deal.
Goblin Mech (max lvl) -> Usefull in some ocasions due to stun, normally I would take in a knock-out rule attacking from anywhere
Scavo Hireling (max lvl) -> Good support once it gets slow and cammouflage.
Venari Spellsmith (max lvl) -> I started using it and thouht vert good the redemption and amplify, does his job on first round.
Xenith Monk (max lvl) -> I started renting this season too. Its a must, Idk how many differents battles I was loosing before and winning now. Like in the 4 max mana.
Gelatinous Cube (lvl 6) -> Very good to gold league at this lvl, actas as secondary tanker or even last survivior auto healing a lot after stack scavenger. Interesting card.
Sand Worm (lvl 1) -> At this lvl is only usefull in high mana reverse speed melee only.
Spirit Hoarder (max lvl) -> I use a lot, blind and triage makes his an execelent support for 3 mana.
Disintegrator (lvl 5) -> Demoralize and trample, a necessary card in many situations.
Chaos Agent (lvl 6) -> I started using this season, does a good ammount of difference for a 1 mana card.
Uraeus (lvl 4) -> Good sneak dmg, 3 speed, and poison. Can fill low mana spots.
Furious Chicken (lvl 1) -> A bait, thats it, but still is must, imagine go with one less spot?! Lol, one hit can be the difference in a game of details.
People always asking stuff about deck when I say I rent cheap for diamond, so I decided to drop the decks. But yeah, but with new meta might be better go only max and trying to upgrade. Need to do a good bankroll before. But seens like rewards are very nice if you can play in champion.
