I started Arena last week. One thing I noticed was how it decides what you can and cannot play. So say T1, I drop a land and i don't have a 1cmc spell. It'll just jump to pass turn. if say I have 3 lands open, and coming up to my 2nd main I have nothing but 5-6 cmc spells, it'll just jump to pass turn. Doesn't this take away from the bluffing aspect of the game?
It can take away this aspect, but if you want to have that you can turn on full control and it will ask you to pass priority every time. The default is great for new players who won't even understand bluffing and as you learn you can choose to enable and disable as you choose adding more layers of bluffing as you toggle it on and off mid match.
