I play in casual matches and in competitive matches. People have suggested limiting to 3 before. I think that's too little. 5 seems good enough if you allow a normal and a pendulum summon on top
It should balance the game properly
Not that Konami would ever do this
The more I play the more I see an issue/potential solution with the current way Yu-Gi-Oh exists
Special summoning half your deck is too easy. That's a fact. Lets limit special summons to 5 per turn. Not counting the pendulum summon.
You could have cards to increase the limit
I know it may be an unpopular opinion because 'was wah my combo deck needs 8 special summons'
Oh well, do it in 2 turns rather than one. Deal with the opponents set up and counter play
We shouldn't be stuck relying on hand traps to save us from a turn 1 unbreakable board
