It would be best to always have at least one Enchanted Javelin set on the field, Arkana would choose to attack The Unhappy Girl if his attacks would bring your life points down to zero, so having Enchanted Javelin set would most likely stop him after his first attack.
Once you summon Mythical Beast Cerberus, you can start increasing its attack by using Spell Cards. Your target is to immediately increase its attack by more than 2500 so Dark Magician can't surpass it.
On your final turn, leave 1 slot at your back row, set 2 unusable Spell/Trap and put a Field Spell Card. You can then use Storm to destroy all of your opponent's back row cards. This prevents Arkana from using Dark Renewal when you summon Gravekeeper's Vassal.
Finally I got the card I want. But there is still the Mystic Box :D

Consistent 7000+ since day one and I got no Anti-Magic Arrows, but hey I got 4 Diffusion Waves, 2 Mystic Boxes and 2 DM.
Seriously If I can't get even one drop of Arrows for this events I might as well stop playing. They release RE insight and I can't get it and now they are doing this again to me. No point in playing pvp at all when I can't even use optimized RE deck or ANY Beatdown decks.
I battled lvl 40 10-15 times and all I got is rares and not a single super rare...its been 3 days and not a single drop from him ...wtf is this konami?all im getting those fucking stones...im dissapointed with konami...like the super joey event he hadnt dropped a single insight for me...im going to give up on this game now if they dont fix this shit
