how do you use a spell card five times

god how stupid you guys are, it just need to use 5 spells in single duel ffs.
here is the guide for idiot:
1. Fought low level duelist (either LD or SD) so you can easily control their LP and prolong the battle.

2. Damage them, but dont kill them yet, just make their LP around 100-1000 or whatever.

3. Just keep spamming a non-continous spell card, I'll say it again, A NON-CONTINOUS SPELL CARD, so you can make a space for the next card.
If you somehow use an Equip Spell Card, just tribute the monster to destroy the equip spell card.
Never use Continous Spell Card, its hard to get rid of it, so if you "somehow" (again?) used it, dont be stupid, bring some despell or twister you idiot.

4. At this point, where you keep spamming a spell card, do not attack, Do NOT ATTACK enemy's monster, their monster just gonna filled up their space, and just ignore it, Ignore It ffs.

5. After you are sure that your spell card already used like 5 times (or so what the mission ask), attack the enemy adn end the battle for sure.

That's it, u can ask me if you dont get it

Tried banner of courage, card trader and mask of the accursed. No use. The mission still stands. Stupid bug!

It's not working .....any other way ???

you don't have to use the same spell card, you can use whatever spell you want, just use 5 spell cards in one duel to finish the quest

I've used the tips on this page, using the likes of Wonder Baloon, Banner of Courage, and Card Trader, but nothing works. Any further suggestions?

Are you sure you did as i said ?

Its not working for me ....can anyone help ??

BANNER OF COURAGE, use it with three monters, battle with other monster in defense so you won inflect damage, and wait until the other player decks runs out

eventually*

I used it until the other dduelist cards run out, eventuallt will work, in my case worked out first time but will receive this mision on other stages, where i succeeded after four duels, so it s working but i think that it a bug from game
