Doesn't duel links have stricter deck and extra deck requirements? 20 card main deck, 5 extra deck. Deck size does matter to be honest. If applied to real world speed duels would be full with ftk's.
Also I'm not a fan of speed duels, there are several issues that barely will be adressed because anime but you can already see that the cards aren't really made for this kind of duels.
Take for instance decode talker. Decode talker is a link 3 with up,left diagonal and right diagonal link marks. Due to speed duels there is no position where decode talker cannot use its full potential.
Let's not forget pendulum summoning having, 3 spell and trap zone where 2 has to be pendulum zones means they can barely play a trap without locking themselves from their spells.
Or what about ojama's? Ojama king locks 3 monster zones. RIP.
Basically trying to make speed duels official will never work. Skills which is another element of speed duels. If they don't watch out skills, they might be the action cards of vrains.
You already see they replaced pot of greed wih double draw which action cards did as well. There is a reason pot of greed is banned and placing this skill in practical situations is just asking for abuse.
This skill would be forbidden in 5 seconds.
For the anime it ill work I guess, skills will be the element typical to anime. Whther it be deus ex machina cards, pot of greed/xyz gift/speed world 2 and sshitty traps nobody in their right mind will use.
The potential problems with speed duels will never occur. Oh well. Honestly it's just unnecessairy.
