Depending on the match up can determine your skill order.
Can do WQE or WEQ or WQQ.
You can harass with your W your Q or with auto attacks and procing the E passive for the extra magic damage.
You can last hit really well too if you have to play it safe by just spamming Q and blue cards. Once you get comfortable, you can last hit and harass at the same time with Q.
You don't necessarily have to get kills in lane but its super easy to coordinate with the jungler to get kills. Can get a stun card and use flash then have jungler follow up.
If you can't get close to land any auto attacks or they dodge Q's too well but they stay in the mage minions, you can red card and the damage/slow will hit them then you can follow up with a Q then blue card for mana back.
post 6 you can use destiny to gank lanes/jungle. You can cycle cards during the ult/ lock a card or lock card before ult and have time to land the attack. Just be mindful of how much time you have before it expires. If you get zhonya's you can bait out abilities/summoner spells by ulting into the middle of an enemy team and using the item then have your own team follow up immediately.
