Setup G Suite and Mailgun to receive email

I would like to use both G Suite and mailgun to receive email.

For example:

For this I am pointing MX records of bla.com to G Suite and then routing unknown emails to mailgun using MX from another subdomain mail.bla.com

However I get the following error 

Google tried to deliver your message, but it was rejected by the server for the recipient domain mail.bla.com by mxb.mailgun.org. [104.130.177.23].

The error that the other server returned was:
550 5.7.1 Relaying denied

You should definitely never use multiple MX records on one domain.

You will confuse the servers which finally leads to inconsistency in your email traffic.

According to mailgun subdomain + MX records is one possible path to take.

Trying to do the same thing, I found that relaying for a domain will only be allowed, if it has (additional) MX records pointing to mailgun servers. Once mailgun had verified the MX records, I deleted them and relaying continued to work. However, it is unclear for how long, as mailgun may periodically attempt to re-verify them. Clearly not something suitable for productive use.
