Youre looking to combine goblin payoffs with cheap disposable artifacts here, so include all the usual goblin lords and cards like Skullclamp, Prized Statue, and Ichor Wellspring
Im even excited by the fact that it can fetch up planeswalkers from the graveyard
Chart shows the price of Iroh, Grand Lotus [Extended Art] #2 at the end of each month going back as long as we have tracked the item.
Perhaps going heavier Blue would have been better, as it seems to be the only color that allows you to draw cards reliably (along with Black)
Its flexibility and consistency will probably make it a staple of these strategies for the foreseeable future
To find the likeliest candidates, I looked through lists at popular review sites like Shut Up & Sit Down (video), Wargamer, and Dicebreaker
