So here's the thing with Ivern.............he can get pretty damn powerful.......but he unfortunately he needs help in the disguise of an adc when hes the real deal.Hes kind of a hybrid player when supp when beginning you need to play safe REAL safe as the only thing that keeps you from dying is your wits hanging in the balance.If however you play like me you will be chaotic constantly harassing enemies with your exploding shield and stun move in and out like a ravenous hornet that play style has alot of risk however so only attempt it when you have a definite kill in sight make sure there is no threat of jg coming in to increase the level of threat for you and have your adc join in on the fight hard or to keep the other supp in check this style later on becomes way more viable as your health increases,

Daisy................ehehhehehe................HEHEHEHEAHEHAEHAEHEEHEHEHAEHE............first of I'm not so good at explaining my move set as most of the time I improvise but I do have a certain steady strategy set on my mind first of the Cornered golem- when the enemy has you pinned to your tower with tons of minions around and they (usually ranged like sona with fortune or other combos) are very aggressive and resolute to pick away your health that's when daisy comes in to say hi but make sure to keep daisy under check don't waste her on useless tasks use her wisely.SO you bring out daisy high five and all and you get that ***** up on the enemy like peas and carrots use your shield on her too to slow them down while she keeps the enemy from running with her stun and your shield that's when you show them how truly cruel nature is especially if you root stun then slow them with the shield and use an exhaust if handy but make sure not to get killed as daisy does along with you and your adc is left unprotected.
Second strat is for them enemies who come up to get a free kill on you or the ones who regret it when they do 1-when they chase you use your shield on you if they are close then follow with a quick but well aimed root bring out daisy too so she can stun them and slowly eat away at their health while they still think they have an advantage but split when theres more than one enemies around and so if you manage it soon the hunters become the hunted 2-now theres two things you need to remember with daisy one- she can move faster than champions and two-her stats rise when your ap do so youre chasing the enemy with your op mooves doing slow but steady damage daisy is fast she can more than keep up she stuns use your shield on her to further slow them use your root when both are on cd if its early and you havent got rid of frost queens claim use it to even further slow them down and pop in an exhaust to REEEEEALLY get their blood a-boilin
On another note if the enemy has super low health and your root is on cd use a bush ahead of them and use iverns long range attack other than that the bushes are (but not entirely useless like in dragon or baron fights since the enemy cant directly target you in them or since they have a long range use them as way to figure out where enemies are) useless.
The general gameplay is you protecting your cd and harassing enemies with your root.

He can keep people alive ALOT do note that he can save and keep fighters near invincible with redemption iron solari and even in offense with ardent senser.

Whenever you can.
