If you're looking to claim just these forked coins, then this method may be for you. 

Providing you want to pay for the steel card, you can use Ballet Wallet to sweep forked bitcoins into their in app wallets for BTC / BCH / BSV / BCHA / BTG and BCD.  These wallet addresses are swept at the same time unlike the Coinomi App that will only sweep each wallet that you select one at a time.  TX fees are near nonexistent and like Coinomi you can swap/trade forked for BTC in App.

From what I can tell after installing Coinomi a couple of hours ago, it will sweep with one Priv Key BTC, BCH, BTG, XBC, BSV and BTCZ, but unlike Ballet Wallet, it does not have a facility to sweep mnemonic password wallets.

Either way in under a minute, you can sweep the forked bitcoins variants with either wallet App.  (Tangem Wallets don't seem to have that capability)  I don't know as yet whether the App will create new forked coins later on when they occur, or you need to re-sweep after the snap-shot is taken.  Time will tell.
