About formatting, I think placing this in the original post is usually pretty nice:
You do that with IMG tags; you can quote my post to see how it was done.
Basically, I did:
[IMG.](link to the card image)[/IMG.] without the dots; and did the same for the "upgrade" part and for the Poseidon. It's pretty simple.
You should most likely edit your first post and if possible start a poll with your changes (This is more of a READ THIS FIRST request than my own), such as "Should this card be buffed in this way?" and a Yes or a No, or an option with "This card is good and should not be buffed", "Yes, Poseidon needs this buff", or "Yes, Poseidon needs a buff, but not this one (other)". You can pretty much make your poll look like anything.
The
read this first can probably answer everything that I didn't cover (and I didn't cover a lot of stuff...)
I will refrain on commenting on it now, but I personally think that Water and Earth is very possible, and although I agree trident is indeed very under-used, I'd say it's far from UP.
