I play a similar style derevi deck using the deadeye combo. However, i found that palinchron and perigrine drake are unnecessary. instead I just use derevi as the palinchron/drake because with derevi and a 3 mana producer, one of which is blue allows you to gain infinite mana. This also allows you to focus more on disrupting your opponents and adds room for more stax cards. If you decide to go this way I find Overgrowth is a good 3rd Gilded Lotus . I see that this list is probably alot more consistent with the combo, however.

I also play Derevi $$$$$. Nice work.

Consider Altar of the Brood.

It combo’s with your deck very well.
