So i've decided to talk about Zyra support.

Skill order:

start with whichever ability you have an easier time landing, for me this is Q. the only time you have to take E first is if you are going to invade at lvl 1, if not its your choice. level 2 always take W, this gives you mad harass. at level 3 take whatever ability you dont have yet. from this point on max E, the base damage is 10 less then Q at all levels but the snare increases with level so max this first. after this you are going to want to max Q next then max W last, obviously you should be getting R at 6-11-16.

Summoners:

Ignite + flash 99% of the time, exhaust is just not nearly as good on her. ignite is what pushes your damage over the edge in lane and helps you snowball early. Flash is obvious, you want to flash E people under turret at level 4....well that does happen from time to time its much more likely that you will use your flash to save that leafy booty of yours.

masteries:

Go for AP dmg, get deathfire touch, put 12 points into cunning grabbing movement speed out of combat (once you win lane your going to want to roam ;) and mana regen as well as bandit and biscuits.

Runes:

flat AP quints and glyphs, armour seals (you can go flat HP but i prefer armour) and Mpen reds. You are playing to get kills early and snowball so you want a page that lets you do this.

items:

start spellthiefs and pots->rush Frost Queens Claim->Get morellos->rylias->lyandries->deathcap grabbing sorc boots when you can.

Frost Queens - i have built this item on her midlane it is that good on her. Rush it. do not buy a NLR, dont get the sightstone just get frost queens ASAP.

morello - this item solves all your problems, it gets you to 30% CDR (which is all you want thanks to zyras w) you no longer have mana issues, grevious wounds is always nice on a mage that usually has to finnish champions off with her plants in the midgame and lastly the AP you get from this item is usually enough to make your E+Q kill ranged minions which makes it very easy to push lanes and take towers.

rylias - yes your E plants slow, you dont want to rely on these plants. your Q plants have the same damage and around double the range. This item also gives you tons of AP and enough HP to let you survive in teamfights for quite some time. if you have enough $ for the NLR after you have completed your frost queens you can buy that component before completing morellos as the dmg with a NLR is usually enough to let you combo squishies without relying on your plants.

lyandries- more tank, more AP, Mpen, Dat Passive yo. nuff said

Death cap- This is just for pure damage, you can combo out whole teams lategame with this item. Support pentas do happen.

sorc shoes are good. I've gone whole games without buying them though, position well and use your E defensively if they have someone who will jump on your face. if you have these end game then sell this before frost queen. and buy a ludens or a ROA since its stupid strong right.

stratagy:

In lane, push hard level 1. you want to get the enemy laner under turret so that you can poke them for free without them trading back, zyra is super squishy and this helps negate that.

at level 4 you can usually E+W+Q+W and win lane right off that trade. If they have a healing support like soraka make sure you use it on them if not take that ADC to 1/4 hp.

once you hit 6 your damage is absurd. your combo is not active and you should get a kill the first time you use this. E+W+Q+W+R. look familiar? well its exactly like the trade you did at level 4 except your R does good damage makes your plants into deathgrinders and knocks the enemy up as your root ends. if they have flash they will have just enough time to flash away between your E and your R activating the knockup. in which case throw your R slightly farther behind them. you would rather have the now super low ADC run at you and your adc rather then flash away under there turret and you loose your free kill.

roams/teamfights:

So when do you roam as zyra? well in this meta you become the second midlaner right after bot tower falls. if you manage to take bot tower super early (pre frost queens) which can happen with a junglers help then you still want to roam mid, usually you can pressure mid so hard that you take the tower right around the time you finnish your frostqueens. at that point you want to roam top, no joke take all 3 outer turrets if you can. I've done this before my first back once or twice, plants OP.

teamfighting with zyra is all about getting close enough to root the enemy carry and keep your plants in the middle of the fight while staying far enough out of the fray to not be snapped like the twig you are. that being said you are a support so if you can blow up an enemy carry and have to trade for it its really not the end of the world, you can usually get 2 if you land your passive.

pressure:

zyra is an oppressive champion, as a support i usually win 1v2's. use this to your advantage. now im not saying go looking to 1v2 the enemy team, what im saying is once they see your damage they are going respect your plant booty or die so your role becomes less about getting picks and more about walking up to a turret dropping a w and AAing it. If they walk up you now have 3 plants ready and kill them or they let you drop free damage.

As zyra you can push lanes fast. Drop a W in the melee minions and E+Q the ranged, the lane will push hard and you can usully take your own lane in the midgame. yes its greedy of a support to do this but you want the farm and you want to draw the enemy to you. again you can 1v2 so they will be sending 3 champions your way which means free objectives for your team.

Tips n Tricks:

use frost queens active before you do your combo, the slow means they have to flash the E if they want to live.

if an enemy champion uses flash in lane they are your target for the next 5 minutes. the root lets you get free damage off.

place a right in front of the enemy ranged creeps, This forces the enemy laner to play really far back or stand to the side of the creepwave which makes it much easier for you to lane your E.

you can take dragon super fast while your team takes little damage. place your W's at 45 degrees left and right behind the dragon, then make them into plants. they each take 2 AA's from the drag to kill and by the time 1 dies you will most likely have anouther W ready.

BUY BLUE TRINKET. you want to ward? do it from afar you are to squish to get near any bushes.

tl;dr Zyra is amazing go read what i typed
