If you are leashing don't forget to use your W – Ferromancy - Crash Down / Mount Up (Crash Down) and tank with the shield, and then use your W Mount Up to get in lane quickly.

Always remember that your passive Break the Mold steals resistances on your AAs, it may not seem like much but it will come in a clutch in many cases.

Your Relic Shield will execute minions under 50% HP when you AA them and have a charge available, consuming said charge and giving both you and nearest ally minion gold,and generating a charge every 35 seconds. It is recommended to not waste your charges on first wave of minions, and instead wipe out 3 melee minions of the second wave, not forgetting to take cannon on the third wave. It is not recommended to use your charges on caster minions unless your charges are maxed out.

It is very important to use your W – Ferromancy - Crash Down / Mount Up (Crash Down) to engage level 1, because of your shield and Aftershock it will be hard to not get a good trade out of it if you land it. When you get your level 2 you can engage another time with W Mount Up flipping enemy over yourself and stunning the with E – Full Tilt. When you get your Q – Shattering Strike you can use it to break enemy shields or for sustain if they don't have any shields, remember that if you hit two champions with your Q, heal will be twice as big. Also your Q – Shattering Strike applies your Passive Break the Mold to the first enemy hit.

Once you hit level 6 you unlock your R – Magnet Storm, which can be paired with W Ferromancy – Crash Down to pull enemies into your Knock Up, and then drag them in favorable direction. Remember that initial pull from your R also cancels dashes like Thresh's Flay does.

Objectives are probably one of the, if not the most, important parts of the game. Baron Nashor and Rift Herald make pushing really easy, while Drakes make champions much stronger, especially the Elder Dragon, skyrocketing whole team's teamfighting power.

You need to work with your team to get these objectives, make sure you Recall pre-emptivly before an Objective spawns so you will be here in time. Rell is very useful for taking objectives, as she offers great zoning and CC tools for her team.

The classic combo consists of using Flash/Hexflash>W>(Optional Mid-Air E)>R, after landing you can use your AAs and Q in no particular order.

The second combo can help against more mobile enemies, it goes as follows: R>Flash>W>E(Mid-Air). This one is a little bit more complicated and costs you some CC duration, but is much more effective if enemy has some mobility spells or Galeforce up.

Both combos can be applied in variety of situations, be it engaging on enemy Botlane during Laning Phase, or engaging on enemy team from behind a wall during Late stages of the game.

Fast Ward Kill

All you need to do for this one is being Unmounted, hitting a ward, mounting up and hitting a ward two times, as your Mount Up AA is Auto Reset, kills on revealed Stealth Wards will be almost immediate.

Killing Wards Over Walls

For a Melee chamrion, Rell's AA Range is pretty decent, at a respectable 175. This range allows you to kill wards over some walls if they stand close enough to them. All you need to do is position yourself near the visible enemy ward and start blasting.

Pulling Self Over (W)all

Using the information above, you can apply the same strategy but using your Mount Up, as it will make Rell charge(AKA dash) at the target, making you able to hop over a wall attacking a Ward or Enemy Champion, additionaly making it easier because of increased AA range. Be aware though, doing so with Enemy Champion may flip them to your initial position.
