Visibility is something that should be looked at going forward

So what I mean by that is, matching based on faction/type is made much harder when the only thing you have to go on is small white text. Particle effects such as a purple void glow for voidies and a frosty border for glacial champions would make a lot of sense. The rarity colors are at huge risk for confusing people, as sometimes the colors align with the creature's faction, such as Volibear being a "Glacial Blue".

To remedy rarity clarity (heh, rhymes), I suggest using the rarity jewels from the hextech crafting system. Commons get nothing, rares get the blue gem, epics get the triangle gem, and so on. Also, getting to mouse over attributes in the buy list would be very helpful, as having to buy them first to see what they do feels bad.
