This eight-cost character quests for four lore, which is already a huge amount, but anytime it does quest, you get to ready all the cards in your inkwell
Goblin Engineer is clearly the WoTC approved fixed version of Stoneforge Mystic, but the card is powerful enough that it will see play in Vintage, Legacy, Modern and Commander
When it comes to abusing lore counters in Standard, one card clearly stands out over the rest: Animation Module
Starmie V with Misty (#083, CSR)
During your opponents Main Phase (Quick Effect): You can Fusion Summon 1 Fusion Monster from your Extra Deck by banishing this card you control and monsters from your field or GY as material
(And keep in mind that instants, sorceries, and enchantments that create tokens don't count for this.) If you're going to go tribal, make sure you're taking full advantage of the tribal cards you're working to play
