Drawing cards with your free spells is all kinds of silly, and its a good way to make up for the card disadvantage of having to exile a card from your hand to cast them for free
But the games now filled with salty cards and salty players, and at least Iona lets me know its time to pack up my stuff, unlike Dockside Extortionist or Esper Sentinel, which tell me Im going to lose in two hours, too late to join that draft pod over there
Thanks to that, it actually has a fair few commanders who can each focus on a different part of the original decks themes, should you choose to break it up: Barret, Avalanche LeaderBarret, Avalanche Leader Aerith, Last AncientAerith, Last Ancient Sephiroth, Fallen HeroSephiroth, Fallen Hero Its just a treat
You still always play Guide in your aggressive decks with red mana in them but you are not so sad when you have no Guide to put in
It essentially functions like a 4-mana 6/6 with haste and flash, making it super good in combat
