Basically:

1. level the Rare (some of the best non-event ones being Megatron, Grimlock, Shockwave, Optimus Prime) if/when you get them. If you get any Super Rare from the space bridge make sure to level them.

2. don't level common or uncommon (unless you want to collect data for the wiki).

3. Aim to MTM your card deck (max level both robot and alt mode, fuse them and max it again). This gives you a higher overall stats.

4. Participate in PVP to get Battle points for free weapons (although I mostly grind Decepticon mission 2.3.4)

5. During Events remember to save some battle cubes for the last day
