Stamp Sea Otter

Welcome to my first card discussion.  Here is the topic card: and here are my thoughts:

+Being a rearguard immortal, you can spam your Great Nature boosting skills to make this a +10k booster, and it'll not die at the endphase from the boosting.
+If your opponent uses the retiring skill of Amon, you can choose Stamp Sea Otter, and it'll not die.
+its a cute otter.

-I wish it wasn't a promo. Then it would be easier for me to get.
-It's non-retiring skill kinda defeats of purpose of Great Nature. You want your units to die so you can gain bonuses from them.
-concerning its skill, I think a 6k body is a little too strong.  A 4k or 5k body might be a little better, though.
-its a bad idea to put this in a front-row circle. Don't do that.

What are your thoughts about the card? Should you use it for Great Nature? Should you not use it? leave your opinions below.

I honestly dont know jack shit about great nature but that card on its own is a good concept since it can nullify some of the units that retires rear guards like "Blaster Blade" for example giving u more possible guarding options since you dont need to replace the "retired rear guard" anymore.

I'm not saying it's a bad skill, in fact it's a really good skill. My main complaint was that its in a clan that REQUIRES your units to be retired for draw power/damage unflipping.

on the flip side, Great Nature works by giving rearguards +4000 power, and then retiring them at the endphase. This card becomes a nice abuser of those boosts and wont be retired (ya know, as long as you're not stupid enough to put it in front row.)
