Ordeal of Thassa - http://magiccards.info/ths/en/58.html
I have my Battlewise Hoplite in the battlefield with 3 counters on it, i cast a Ordeal of Thasa. What does resolves first, scry or draw?
Thanks in advance!
Autocard is easier: [c]Ordeal of Thassa[/c] = Ordeal of Thassa
You cast Ordeal of Thassa. This triggers Battlewise Hoplite's ability. which goes on the stack on top of the Ordeal. When it resolves, you put a +1/+1 counter on the Hoplite and scry 1. Then the Ordeal of Thassa resolves. That's it.
Later on, when you attack with the Hoplite, Ordeal of Thassa's ability triggers. When it resolves, you put a +1/+1 counter on the Hoplite and count the +1/+1 counters it has at that time. If it's three or more, you sacrifice the Ordeal, triggering the Ordeal's other ability. When it resolves, you draw two cards.
The key thing you're missing is that the Ordeal only cares how many counters there are at the time its triggered ability resolves (i.e. when the enchanted creature attacks).
