Well, I don't think the battles are particularly impressive, unfortunately, but I love King Erminaz! It's a very effective hammer.

Here I have one win in Frontiers

I like this battle in particular because King Erminaz gave the final blow.

Another one in Modern

This battle in Modern has a particularity that it were only Melee cards. So it was an opportunity to place two sneak hammers in the back and a bunch of opportunity cards. In that sense, King Erminaz and Sehrringham Logger make a great team decimating my opponent's back.

Heck, I even use it in Survival!

Although this is not a particularly good battle, the effectiveness of King Erminaz makes it a great card for Survival. By the way, I love to combine it with Incessant Sage summoner because he gives to all cards and extra +1 Armor and that is something that King Erminaz unfortunately lacks. But with that combination it makes him great not only to attack but to defend against your opponent's blows.

Conclusion

I love how versatil King Erminaz is in battles, I can combine him with other sneak cards as in the Modern battle, use it as a tank or just as protection for your rear line. I use it all the time and have fun with it!
