Why didn't anyone use this card?

hey guys so I'm doing card reviews like Shooting Quasar except itll be on cards that werent played alot but deserve to be played so heres my first one

All synchro monsters on the field are changed to defense position and at the end phase ALL synchro monsters are SENT to the extra deck. So I know there would be a risk of hitting ur synchros but i think it would be worth it.

If you have feild pressence with your Synchros then it would just sit there and do nothing but i see your point of it not being played that much.

Well this card is now dead due to the fact very few decks use synchros now

Thats not really true but this would make a really good side card going by what Yagami said because most decks now are either mostly synchro or mostly XYZ even if they run both for any scenario.

Quite a crazy card, was this around when it was just synchros?

only 5 or less percent of the ppl on DN are playing a deck that is build around synchros as main. Its a lil bit like mask of restrict, a card that is only good in the format it camed out in.
