Why can't I trade this Powersaved Entei away?

Why can't I trade this Powersaved Entei away? - Diligent black female worker setting signboard outside cafeteria at sunny day

I've made a whole box of cloned shiny Entei with Powersaves, and I'm trying to Wonder Trade them. I've seen so many Pokemon like Shiny Arceus being traded onto WonderTrade, why won't this Entei?

The Entei is nicknamed "King Sacred" and is holding a Choice Scarf
Stats: 180, 134, 125, 124, 149
Ability: Pressure
Nature: Adamant
Ball: Premier Ball

Sacred Fire
Iron Head
Stone Edge
Bulldoze

I cloned all of them, and they're not trading away. When I attempt to trade them on Wonder Trade I get the message "COMMUNICATION FAILED"...

I also have another Shiny Entei that is Adamant, Pressure Ability, with Stats: 314, 208, 178, 197, 282

Extreme Speed
Howl
Flare Blitz
Crush Claw

Should I clone this one instead of King Sacred?
