I’m confused as to why hosts consecrated by a Christian church would be important to satanists?
Catholics and Orthodox believe in the real presence of the Eucharist.
It is therefore an attempt at committing the gravest possible sacrilege to desecrate the consecrated host containing the real presence of Jesus Christ’s Body and Blood.
In effect, theologically, it is like betraying Jesus to his enemies with a kiss.
The simple answer is that Satanist believe the Body, Blood, Soul and Divinity of Jesus Christ reside under the accidents of consecrated bread and wine.
As far as I know, and could be wrong, only Roman Catholic and Orthodox believe this.
Not just hosts consecrated by "a Christian Church," but specifically hosts consecrated by the Catholic Church is what they're interested in. This i because they wish to express contempt fo God, and God is really, sacramentally present in the form of bread and wine consecrated by the Catholic priest.
The satanists don't want something "symbolic." They want to truly desecrate the Body and Blood of Jesus Christ Our Lord.

No need to be confused. Satan knows very well who Christ is and also knows very well His presence in the Eucharist.
Not a Christian church, but the Catholic church. The Catholics believe it’s the real presence of Christ, apparently so do the Satanists. They need the REAL body of Christ for their sick intentions.
