Well I think I should introduce myself so: Im Simimenco and this is my first guide ever, im in Gold 3 and I reach Gold 1 (I know im bad but mechanics are not elo based), The reason I choose Senna for my first guide is beacause ive been spaming her since she was released and test on her ALL the runes and ALL the matchups possible and I like to share some of the things I discovered with you guys.

Senna is the first support/"marksman" but for my is an AD range supp, like Pyke but with Range xD, she is the dead wife of Lucian that came back somehow :v, well If you are here you might know the basic of her abilities and that stuff, but I tell you some tricks that you can do with those later in this guide.

Q: Your Q can be active with anything, wards, enemies, allies, minions, monsters, turrets, enemy generated structures or mobs and souls from your passive, so if you want to take the best use to poke use minions in lane or in there are any and you see it worth use a ward as a way active your Q and hit the enemy by surprice, also other thing is that the Q deals damage to enemy turrets (the cast of your Q or your AA is not interrupted if you use flash).

W: your W is your way to engage and a little trick is that you can flash while the W is casting (is a short cast) and the W will go in the direction you have the mouse, this can be a really good strategy especially in early to do a hard engage and don`t let the enemy time to react.

E: during TFs activated before entering and as soon you can, this can be the diference between life or dead, it also grants you move speed that combined with your Yoummu if really fast.

R: well, try to use it when is a fight that is even in other lane, you can ensure the fight and get an assist, if you flash while ult is casting it happens the same thing that happens with Ezreal`s ult, this trick is specialy useful if the enemy is really close to you like a melee, you can reposition better and get safe, beacause you are squishy and casting your ult is really risky in the middle of a TF.

Well this is the end of this guide, I dont want to make it long and full of info you dont care so I just cover the Basic of Senna`s hidden power haha, well I hope you enjoy it and vote and leave a comment if you have a doubt and I will answer it, have a nice day full of "victory".
