nope...not in my mind...you can win some leggo books or sacred shards...IF you are extremely lucky....
The chances for pulling 3 epic cards in a row is like ((1o/40)*(9/39)*(8/38)) with a full set of cards. So the chances are about 1,2 % to get the high reward with the first 3 cards.
Than you stil get get a barrel or 5* chicken or whatever...
Overall...the rewards from the single cards are miniscule (drew an epic card with my first pull and got 50 multibattles...which I do not rate as epic reward) and the chances to get something useful out of a possible chest are very slim.
Not worth spending extra ressources just to turn some cards in my opinion.
I'd say it depends a lot on the first few pulls. The important insight is that your odds change quite a lot over the course of the event.
If you pull a bunch of epic cards early (regardless if you hit a triple or not), then the back end of the event gets a lot worse and you should stop.
If you pull a bunch of commons/rares early, then the back part of the event can become significantly better. Let's say you change the density of epic cards in the pool from 1/4 (which is the starting distribution) to 1/3. This doesn't seem like much, but it more than doubles your chances of getting good rewards.
And one more thing: in this event you can stop at any time! unlike typical events where the good rewards are very back-loaded.

Card counting is generally frowned upon by casinos
