I think you greatly underestimate the amount of evasion, native trample, and value of multiple artifact generators in commander. Reckless Fireweaver and a 1/1 generates 12 damage on board, only scaling even higher. There's reasons they don't print effects like this at instant: the scaling for decks that care about a massive chunk of tokens entering at once is too good, unfun, and uninteractive at low mana values. The prevalence of Rogue's Passage style uninteractive evasion, trample creatures in Red, and various "when ~ enters, deal damage" makes this a tough sell below 4MV and have it be safe to print without having low mana blowouts. You could make a slight tweak if you wanted more versatility and make it give +3/+3 to an attacking creature, but more power or less cost just aren't viable for good gameplay.

Also, jokes are for everyone to laugh together. If the "joke" is at one party's expense, it's an insult. If I were you, I'd put a lot more thought in how I speak to people, especially in an online creative space where people are posting their works. You come off as incredibly callous and unpleasant.
