Zelda iz a freakin beast. I h8 fiting the char in general, let alone with the IC's.
Projectile wise .. Desynched Blocks > Dinns Fire.
U have more speed, and more importanly, followup options.
So why is Dinns fire a problem then?
Very difficult 2 airdodge with the ICs.. If the Zelda holds the fire behind u, Nana dodges, but u get hit.
.. If the Zelda lets go early, u dodge it, but Nana gets hit. Jus gotta time it perfectly, not much else u can do. Jus make sure if stuck in the air u get 2 the ground ASAP.
Zeldas priorety is pretty beastly, jus dont even try 2 beat it. Approach safely, IB's and Blizzards.
Plz, dont roll too much, her Dsmash WILL punish u. U gotta stay unpredictable.
Zelda Usmash > IC Dair..
Zelda Utilt > Ic Nair..
Make every grab count. Seriously.. If u cant chaingrab well, IB Lock ownz Zelda. Once shes off the stage, jus keep Blocking, she may mess up the UpB.
Thats all I got really.. Jus mix it up, make every grab count and DI!. I believe its possible 2 Smash DI out of Usmash and Mayb Fsmash. I 4got.. Good Luck.
