Yes, Yes, im recommending heal and ghost. while many view these as lesser spells and frown upon them, these have saved me as skarner countless numbers of times and if used correctly it will save you too. Heal, for the obvious fact that it heals you is great when used with a maxed out Crystaline Skeleton. you gain a shield worth of close to 900, and heal for 400 while its up. this scares the hell out of up to 2v1s because you all out block an ult and some basic attacks and if youve been holding out on them till now theyre probably low on health and will try to run. this is where the passive movement speed off of W comes in handy, and if theyre just a little faster than you are, ghost is the sure fire way to catch up to them and get an easy double or triple
