When using the flip tamiyo ultimate ability on mobile, drawing half the cards in your deck works just fine. The issue that stems from this is on mobile there is no way to scroll through your hand after this happens for some reason. The cards also appear very distorted and this may be a contributing factor to the issue. Restarting the app does not fix the issue either. This may be a low priority but this needs to be fixed, there are countless games I have lost due to this bug and having the correct card "just out of reach" so to speak.
