Í start with afor the extra armor, health and health per. 5 sec. thats pretty good i think, because then he can go for more fights without take heavy damage in early game.
Afteri go forfor the extra movement speed.. this item works good forso you easily can catch the enemy, and do some serious damage. Then i go forfor the extra armor and magic resist. now you have a well working tank for the middle game. then i go forfor the extra damage and health. then i go forand finish the build forNow you will be a perfect Tanky, DPS. and you will be a tough target to kill. At last i go for. it works good withbecause the damge is further with critical strike chance. now you can almost survive every fight. who isn't scared of Garen - The might of demacia!?

when you get into a fight you start withand then use yourso your target cant use any abilites for a short duraction, and then you useso you can do some heavy damgage to the enemy. then you just chase the target enemy with some autoattacks. and when youris ready again you use that ofc. then you useagain, and you do this "combo" till your target is on low hp. When your taget is on low hp you use your ultimate,to finish him/her off. your ultimate is also a great way to kill steal if you want to ^^
