You're absolutely right Optimator! I've been struggling about whether I should cut Quest for Ula's Temple or keep it in for the flavour and potential reward, but it has been underwhelming in every game played so I might as well get rid of it instead.

I'm quite happy with the Ramp package I've got so far as well, and I'm not really struggling with casting any of my big sea-monsters.

As for Quicksilver Amulet , as mentioned above, I've never really struggled with casting my big guys. 9/10 times I will cast my commander on turn 4 and then I'll be able to pretty much cast any creature I'd like.

I think I'll add in a nice finisher instead, such as Overwhelming Stampede to close out some games faster.

Thank you very much for your tip and suggestions!
