In the if list, you can use normal commands (e.g. scp), the [[ compound command, or the test and [ builtin commands which in turn need "conditional expressions".
You don't deploy either. [ [ is not a valid construct, and your shell will have said so. Even if using the correct [[ , it would interpret scp as a string, not as a command to be executed.

parallel-scp - parallel versions of scp
SYNOPSIS
parallel-scp [OPTIONS] -h hosts.txt local remote

pssh provides a number of commands for executing against a group of computers, using SSH. It's most useful for operating on clusters of
homogenously-configured hosts.
parallel-scp copy files in parallel to a set of machines.
OPTIONS -r --recursive
recusively copy directories (OPTIONAL)
-h --hosts
hosts file (each line "host[:port] [user]")
-l --user
username (OPTIONAL)
-p --par
max number of parallel threads (OPTIONAL)
-o --outdir
output directory for stdout files (OPTIONAL)
-e --errdir

EXAMPLE
The following example runs hostname on three machines (IPs or hostnames) specified in the file ips.txt using login irb2 and saves the
output in /tmp/foo.
# parallel-scp -h ips.txt -l irb2 /etc/hosts /tmp/hosts
Success on 128.112.152.122:22
Success on 18.31.0.190:22
Success on 128.232.103.201:22

o PSSH_HOSTS
o PSSH_USER
o PSSH_PAR
o PSSH_OUTDIR
o PSSH_VERBOSE
