Is the White alpaca card just a skin for mount or does it affect stats of mount too? Hopefully the former rather than the latter.
The Alpaca provides +10 stat boost (like the 2 steeds currently for sale in shop) and also increases your lvl limit to 25 (was 20).
You can do the 5xwhip over and over again and get 1 shard each time.
Indeed the 1shard description is incorrect on the forum - you get rune packs so not gem packs.
A plea to the developers to be more specific as I as well have lost balen due to the posts not being accurate enough.
On another note do not use the 700 balen and expect 4 shards! it is 1 shard for each 5 TRAINS.
