Fork balljoint splitters get a bad rep as often they're the wrong size and badly made - I've got a really old williams superslim one - never fails and doesn't ever rip rubbers either, unless they're truly rotten in the first place - (nothing to do with me but one on fleabay at the moment https://www.ebay.co....97355181?chn=ps ) that said scissor types are good too ...
The laser flywheel puller is pretty good - but I along with probably plenty of others have busted the odd one....for a couple of uses it'd probably be ok so long as the flywheel is not a particular sod (they can be!)
Very few special tools needed for a mini thankfully - the only specific ones in my toolkit being cone and bendix gear compressors.
In general terms a selection of quality imperial spanners and sockets (in both 3/8 & 1/2") a bucket full of penetrating oil and a huge breaker bar will see you done easily........
A decent brake adjuster spanner worth every penny though.....
