ARAM Trinket Items Suggestion

I know ARAM is for fun and not to be taken too seriously and stuff... But still I'll just leave there this suggestion for possible porocake substitutions. Those would be "trinkets", stored in the extra slot, purchasable only one of a kind and one totally. Main is the point of the items and their actives, stats and costs are just "placeholders" replacable by whatever more balanced.
