Idyllic Tutor out for
Heliod's Pilgrim limits your search a bit, but provides you a body to block/enchant at the same cost and speed.
Grim Guardian and
Wicked Visitor would help close out the games quicker. Incidentally,
Knight of Doves and
Screams from Within combo off and win the game for you if you have either of the former pair. Screams' return effect does not require an initial target, so you can stack things so that the knight makes a bird first then enchant it to loop endlessly. I'm not entirely certain on what to take out for any of this though.
I just noticed you have
Warehouse Tabby, which accomplishes the same thing as the
Knight of Doves with
Screams from Within. So you definitely want to try to get one of the two things to damage on ETB/LTB, if not both and the knight for redundancies in the plan.
