Combined with Cauldron Familiar and any kind of sacrifice outlet, Samwise can create infinite Food tokens, and infinite damage, incredibly easily
Having cards with Flashback wouldn't also hurt in any case Delirium doesn't trigger
Job Select When an equipment with job select enters, you create a 1/1 colorless Hero creature token, then attach that equipment to it
You can test a deck before spending serious money, build a casual Commander list without selling a vital organ to the Reserved List, or create a cube where everyone gets to play powerful cards instead of watching one person shuffle a mortgage payment
You can do a lot of powerful things with Family Matters alone, but it's also one you can upgrade to make it even better
Im definitely looking forward to seeing this card in action in several of my decks
