Stand
For playing on a desk, or watching guide videos while you learn.
What it changes
Holding a tablet for a long session is tiring, so being able to set it down saves your arms. The other use is learning: run a guide video on one screen while you check builds or positioning on the other. An adjustable angle lets you match your desk height and eye line.
What to look at
For a heavy device, look at base weight and footprint. Stands that adjust both angle and height work on a desk or on your lap. Folding models travel. For video watching alone, a case with a kickstand is usually enough.
