Card First Impressions

The card Dark Ha'On Strikes me as more of a defensive tank instead of offensive tank. Not boasting very much attack for 10 mana it makes up for it in survivability (with flying at lvl 1 and scavenging at later levels). While 2 attack isn't going to do much mayhem in the front line usually, Dark Ha'On more often than not will survive more than 1 round of being battered by a mostly physical based lineup as opposed to a magical one. A good card to distract from your backline, or frontline. To center the enemies' attention elsewhere. This can make or break you lineup, sometimes focused attention on 1 unit is exactly what you DON'T want. However, unlike Magnor or the Kraken Dark Ha'On boasts only a meagre 2 attack power. Overall a good defensive tank, but it won't be punching any holes in the frontline anytime soon.
Placement And Strategy
Typically I place Dark Ha'On towards the front so he can absorb (or dodge) the most attacks. Or sometimes as a twist I will throw him somewhere backwards to allow a brutal glass cannon in my 1rst position to destroy the frontline one by one. It really all depends on the ruleset. In the battle located here. The equalizer ruleset worked in my favor for this match. Dark ha on vastly improving the hp of numerous cards on my side. Additionally blast being in effect actually lets a 1rst position damage attractor only damage 1 secondary target. Instead of 2 secondary targets as is the case with the enemy kraken.
Over the course of a mere round the kraken is left destroyed and dark ha'on is still standing at 8hp. A large portion of the enhanced survivability coming from Mimosa Nightshade's defensive abilities. A good counter to magical blasts or reflect.
Due to in effect having the bigger damage sponge it took for time for the frontline to giveaway. Ancient lich also having life sap lead to a rather hp heavy lich obtaining hp from multiple targets. The enemy frontline quickly melts away after spellstorm delivers a decisive final blow to the kraken.
Dark Ha'On eventually dies in round 3 as the first casualty, meanwhile the enemy lineup has become significantly reduced without their sustained damage absorption offered by the kraken.
Blast damage then pummels the enemy as they crumble to greater numbers, blast working in my favor. The dominos fall quickly and by round 5 the enemy lineup is eradicated and Dark Ha'On is the only creature to valiantly sacrifice itself when the dust is settled. Mimosa additionally helping by removing the backline water elemental's ability to heal, this could've been a bit of a headache to deal with considering the 14 maximum hp would have greatly improved the damage healed.
Conclusion and Talking Tidbits
In conclusion I would say Dark Ha'On is a very utile card. Able to channel damage into one location (for better or worse). If Dark Ha' On is predicted it can lead to a ghastly outcome. Tread with care, snare can be your ruin. Dark Ha'On is a good card, but when countered can be an easy defeat. Your backline wont have time to respond before damage resumes its natural course. This usually leads to a domino effect of fallen creatures as seen in the battle above aswell. An excellent card, even though it wont be trampling creatures to death like Magnor, or becoming an enraged team devourer like the kraken. It will be offering greater long term sustainability with scavenge, and is a bit harder to hit (Except against snare!).
