I would recommend changing the commander to Karn, Legacy Reforged, as well as adding a good amount of mana rocks like Mind Stone, Thought Vessel, & Thran Dynamo to help get you where you're going
If you find a way to damage your opponent, either through combat damage or with a damage spell (such as [c]Lightning Bolt[/c]), you can play this spell for only one red mana, which is quite the bargain
While plenty of companies offer top-notch grading services for Magic cards, PSA and SGC are usually in the conversation as the most trusted and recognizable brands in the business
This means you can't take something like an Alexander Clamilton or an Ass Whuppin' into Standard, Modern, Vintage, Legacy, Pauper, Pioneer, or any other format
