fake pokemon cards charizard (NEGOCIABEL) COOL GOLDEN RAINBOW VMAX RARE Fake Charizard Card - Etsy

You can feed it your creature tokens and mana dorks after tapping them to cast the spell and then selectively pick off the permanents that are pissing you off

If not, subbing in Saruman as the commander will probably be your first big change to the deck

Put that card onto the battlefield and the rest on the bottom of your library in a random order. The short version is that you get to hit people with things, sacrifice them if you want to and then replace them with the next creature that shares a type from your library

You'll mostly see it in control decks that need something like this in order to remove all the cheap aggressive creatures
