Hello.
Pre-season7 came, and bard got a strong item "redemtion"

(Redemption Introduction)
SO REDEEMED UNIQUE Active: Target an area within 5500 range. After 2.5 seconds, call down a beam of light to heal allies for 130 (+20 per target’s level) health, burn enemy champions for 10% of their maximum health as true damage, and deal 250 true damage to enemy minions (120 second cooldown). Can be used while dead. (Half effect if the target has been affected by another Redemption recently)

(Bard R Introduction)
Bard sends magical energy arcing to a target location. On impact, all champions, minions, monsters, and turrets in the target area are put in stasis, becoming invincible, untargetable, and unable to act for 2.5seconds.Epic monsters are also put into stasis, despite normally being immune to disables.

If your Ult hit enemy or team, your redemption 「「「must」」」 hit!!!

So strong. (but, if enemy has redemption,,,,oh, don't think it.

Your Q is so strong if hits two enemies.
Try to hit two enemies.(if enemy champ is behind a minion, shoot your Q to enemy and enemy champ, he will be stunned and your thunder load occur.
Nothing to say bard passive AA is strong. So you should try AA to champs.

And puts your W near your 1st tower.
If no mana, get chaims with warding.

Your R is strong engage.
Destroy enemie's ward and call jg.
Kill adc or sup.

Roaming to mid lane with jg is a good choice.
Assist mid.

Your Frost Queen makes you easy to hits your Ult.
Or enemy flash down. GG

(((I recommend you to practice R-Q combo. This is so difficult, but if you can, it'll be strong technique.

try to FQ-R-Redemption-Q Combo.
All you need is engage and warding.
