I am a new tps pilot.  I was playing some test games at my local store vs tez.  I was on the draw and my opponent lead with sea, ruby -> scroll for drain.  My hand of 8 was : force, inkwell, dark ritual, gifts, grim tutor, pearl, jet and delta.  I drew the inkwell. 

I fetched a sea, dropped the moxen and tutored for duress.  My plan was to duress and follow it up with ritual + gifts. I drew a swamp and made it through his protection needing both the duress and force.  My duress was drained, so I never saw his hand.  My pile was demonic, vampiric, mystical and seal.  I was hoping to resolve necropotence.  I had 1 black available that turn post gifts. 

Was my line of thinking to greedy?  Since I had four mana available, should I have waited a turn to play gifts as to not consume the ritual?  Was there a more efficient gifts pile? 

I was playing this list (-colossus, +inkwell) : http://www.deckcheck.net/deck.php?id=20536

Thanks!

Razormane is a fine answer for Trygon.  Bazaar him into your yard and weld him in during your upkeep.  He shoots creatures during the draw step.
