New Player! And I love Medical!

[Sunic Mitsarugy]

My friend kind of got me into it recently with his huge amount of cards. But he keeps stomping me with his deck. In all fairness I watched his brother use the same deck and some how using barrier pre a bunch he was able to kill off his main ninjas (kakashi) with daedara and win. very interesting game.

He uses alot of freaking lighting blades too...

My question is do you guys have any tips for a beginner? I always play a healing class cause i don't like to not have the option and i heard about a couple of medical cards that were pretty OP I don't know how to link them here. I want to try a medical deck cause he didn't sound to happy about playing it, it seems VERY defensive and able to out last his huge attacks.

Besides the lighting blades he also uses Sakura Haruno 1355. I'm guessing that'll be one of my main ninjas in my medical deck, almost with Karin, Tsunade, and Hotaru. Maybe Hinata? He told me to try to focus on a few ninjas.
Sasuke Uchiha 1129, How do i beat this effect? it just burns my chakra so easily
Jirobo (state 2) 1314 this was another card i couldn't figure out how to defend against and when he teamed them all up they just power house me.

Anyways I'm new! Hi and any helped or advice building a medical deck would be VERY much appreciated! Also i'd like it to be legal so i could play in tournaments.

P.S. I've only been playing for a few days so bare with me when i don't know certain things.
