the main issue with the card is not the card itself , the main issue is it doesn't really fit in any deck i can remember , for example it would make sense if its charge instead of rush but would be too op for aggro and since its rush its too slow for aggro that want to play card also as aggro count alot in synergy like warlock for example you could draw your finisher or minions that buff already existed cards on field instead you just summon 2/2 that kinda miss with your draw little bit , as for countrol decks sure can become good card for anti-fatigue still i don't find it that useful since control decks have really good board clear if you just want to use 2/2 as trading with enemy

The stats suck balls

grandpa wake up!! its 2019 were faceless 4 mana 7/7 is a dead card and easy to remove duo to how we have x10000 access to alot of cheap removals  , stats doesn't matter anymore only battlecry

I wonder what the portals are, neutral spells? We have never had a neutral shuffle card before

The card metadata is missing race: Demon
(see Portal Overfiend)

Interesting dreadlord art (I think, not quite the normal dreadlord attire) also nice to see more from the artist of Azari, the Devourer

Spirit of the Frog can directly draw Portals with cheap spells.

Neat artwork

Potentially good with Plot Twist

Cheaper Portal Overfiend, so it's much easier to play and also in a time where cheating out 2/2 rush demons can be very impactful.

The Soularium is great with this since any Portal drawn with it redraw a new card.
