Yet, the 29-year-old admits to feeling a lot more nervous about a predicted weekend cold snap causing another postponement of the second-round tie than he is about facing down the East Super League cracks.
His concerned mindset is due in no small part to Lie boss Mark Cameron opting to put his Arthurlie players through their paces with a stiff training session rounded off by a five-mile road run when a waterlogged pitch led to last Saturday's game being called off.
Marks grinned: "I reckon our groundsman won't be lacking for volunteers if he ever needs help to make the pitch playable during the remainder of this season.
"All joking aside, it was a hard workout, but a hugely enjoyable one at the same time which was great for fostering team spirit and getting everyone focused on the Broxburn game.
"They are a top league side through East and will be nobody's push-overs, but we know exactly what is at stake on Saturday and will be doing our best to secure a place in the next round.
"And, with the players and management team we have here, then why shouldn't we feel confident about our chances on the day?"
Suspension rules out defender Mark Blakey, but otherwise Arthurlie will be at full strength and Marks hopes scoring two goals in his last outing against Pollok will earn him a starting nod from gaffer Cameron.
He added: "Guys like Paul Stewart, Chris Dallas and Stevie Dymock make it a very intense competition for the forward-line jerseys here, so to grab a couple of goals in making my first start of the season was massive for me, personally."
In other postponed cup contests taking place, Cumbernauld United duo Paul McLaughlin and Paul Thomson will be seeking to put the Emirates Cup hopes of long-time friend and Dalry Thistle boss Paul McDougall to the sword when United travel down to Merksworth Park.
Rossvale appear too strong for another Ayrshire District lesser light, Ardeer Thistle, while home advantage should help Dunipace progress at the expense of Livingston United, but a closer contest is tipped at Robertson Park where Thorniewood United host the visit of Dundee North End.
Wishaw's exploits in knocking Auchinleck Talbot out of the New Coin Automatics Cup will see them afforded every respect by a visiting Beith, and ambitious Shettleston entertain Cruden Bay at Greenfield Park.
